Thread: high performance 350 chevy buildup???

Tweet

420 HP Edelbrock RPM setup for smallblock chevy. 9.5:1 Pistons, Edelbrock RPM Series aluminum heads, Edelbrock RPM Airgap manifold, Edelbrock's cam and lifter kit, & a AVS Thunder series 650 CFM Carb. That produces 420 HP for about, i dunno ... around $3,000, if the parts in your smallblock are built to handle horsepower in that range, just hook some nitrous up to it to get 500 hp. You could buy a big block, but it wouldnt be as cool lol.

Here's what $7000 will build for you - www.gpzilla.com

Go with a big block for hp like you want, 502 or 572. Even that still won't be cheap. You need expensive bottom end parts to stay together - pistons and rods alone will cost you $1500. Forged crank - few hundred more. Hi-Perf heads - another $2K. and the timing - $2000 to time the valves. Cheaper to just buy a crate motor ready to drop in.

Lower your hp requirement or be prepared to dig real deep to pay for machine shop work, and bullet proof parts.

Tech, Normally when people are referring to a 377 they are talking about a 400 block and a 350 crank. You have to either buy a thicker bearing on the mains or you can buy a spacer which goes between the block and 350 main bearings.
You can buy an aftermarket block which is a 400 block made for a 350 crank. This is a popular motor for race cars. It does not have as much torque but it will turn the RPMs. A 377 is easier to hook up than a 406 or a 383 and it will really turn on top end. this works especially well in a light car such as a Nova where traction might be a problem.

I am building a 379 for my 86' S-10 using a Scat 9000 series
cast steel crankshaft that has 400 mains and a 3.5" stroke
The price is $220 to my door.... I already have a set of Eagle 6"
rods for it also... Debating on which piston to use need 12.5-13.1 compression with a decent price tag. Thanks

tim im going to give what i have in my dirt race car and bleave me its not a hole lot but its one bad to the bone motor.. here it is

350 4 bolt block .030 over ( 355 ci )

cast steel crank 350

heads 350 chevy 96 truck vortec casting 10239906 and 12558062 64 cc they need to be fitted with 7\16 screwin studs and guide plates ported and polished. .650 lift duel springs no dampner.. 2.02 int 1.60 ext you can get the springs from the cam company Vortec "L31" 350 SBC heads (PN-12558060)and 12558062 is about $485.00 cheper if bare

speedway valve covers tall 910-17158 you will have to cut one side of the fins in the inside on covers so they will fit over the stud gurtals

pistons are speed pro forged alum //no hyportec floting pins

total seal plasma coated rings

rods are eagle i beam sir rods or the h beam i have I beam rods

the cam that i use is ful rollor comp cam 301-311-06RRD.95 speeyway catelog part number is 251-19134 heres the specs dur 301--311 adv 265--275 at .050 106 cl lift .614--.615

speedway roller lifters 915-11515

crower 1.6 rockers speedway part 290-73641

the u stile moroso stud gurttals any other the center vortec bolts wont fit

use oil restricters speedway part 915-120-RLR

intake Super Victor" aluminum, high rise, open plenum race manifolds edelbrock
PN-2913

one thing to remember and dont forget this one dial in the cam if you dont have it where the lifters are level on number one and the piston is at tdc it will hit and bend all the ext valves i no from exp the cam specified in this build. is if you install it streight up its like 4 deg retarded it was made back when they didnt grind the advance in the cam.. piston to valve clearce is a must to check...

carb is a 650 dubble pumper

oh yea i have a 2 in 4 hole spacer plate

i had this motor dynowed and it was 492 hp at 6800 and 468 fpt at 4300

trust me its a neck snapping motor its cost is around 2100.00
yes that sounds like alot but you wil pay almost that much for a stock rebuild for yout daly driver if you shop you may get the parts chepper

ps i run this motor in a imca mod and fun it hard up to 7100 rpms

and questions contact me profab motorsports

.First if you are running this in an i.m.c.a. mod. you are cheating.The rules state flat tappet cam only.How do I know you are asking ?Our car finished 5th at nationals this year at Boone Iowa.Heads are to small.A cast steel crank?I give up !!!

Besides the problems of achieving 600-650 hp at the flywheeel, you have to consider how you are going to plant all that power. You will have to beef up the frame, fabricate a new rear suspension, put in a differential and axels that will hold up under that power. It would be a real kick to be able to say you have 500 hp at the rear wheels, but if you cannot put power to the pavement, then what's the use?

Eric- that set-up wouldn't get him in the money here either, I run a 436cid and it's all I can do to hook-up a 516/535 lift with a set of Sportsman heads & 205's. We run the 3/8's oval dirt here in the 15's on a weekly basis & when Nationals come here we don't even bring it out. Ron Jones comes up from Vegas with his stable & is just unbeliveable.
Rumrumm is right, it's a pick-up. 500 hp isn't realistic for the street. Can't hook it up without a LOT of money & then you won't be running pump fuel.
Tim_bo I agree with Techie, get a big block.

guys all i now is what the dyno sayed and what i have in the motor and what is cost me

ps yes i do run it in a imca and no its not cheating if its at a non sactioned track..

im no dum ass ....

let me tell you all alittle about me first im a small buissness owner i used to work for american made race cars building imca mods .. when amrc went out of buisness dec 31 2004. i bought alot of equipment and the amrc mod jig and after months of redesgning i came out with the profab new imca car.. Paul Bumgardner claton in .is one of them that drives one of my cars hes points champion at Lincoln Park Speedway 2005 sponcerd by durabilt .

i am the nephew of the driver of the worlds fastes pinto driver Rick Pope springfield misssouri .

ps im not bragging by all means i just wonted to introduse myself.

thanks tim

I just want to say that a 326 powered, 2-barrel toting, 4.90 running Gremlin would be a famous car and most likely on the web page for the track as a featured car and on about every car mag cover. Powerhouse and any other track would love it. I'd pay a dollar to see it.

You brought up i.m.c.a.I have have never heard of your chassis's,but I have heard of Dirt Werks which is an hour from you.I also did not see any of your chassis's at the nationals.At 490 hp you would not even make the (show) on a Sat. night in Iowa.Good Luck.

american made race cars was originaly owend by danny felcor circle track motorsports in willard missouri bought it from him then i bought the american made race car jig from ctm circle track motorsports and after alot of modifications on the cars now there called prfab motorsports race cars the leggendary larry phillips ran a american made race car sum 20 years ago

ps everyone cheats i dont care who you are theres alot of people running traction control that cant be traced you probly run aginest it who nows maby you run one .. like i sayed everyone cheats some time or another ... tim

P.S.,SSSHHH,Don't tell anyone about the (little black box's).We have been winning for years with them.Whoops,I let that slip.Why is it every time we win we hear, (They must be cheating).If you can't run with the big dog's than you had better stay in the trailer.)

lets see some of those mods. pic., here's mine, i raced with the ARA tour. we had 10 tracks in va. and nc that we ran weekly at. did pretty good with it. built the chassic myself and at the time the oldest driver in the tour. used a camero clip with a 406 cu. in. motor. we had 75 cars signed up for the tour, and ran 32 in each race. finished in the top 10 in points every yr. i raced. want bad for a almost 50 yr. old man. lets see some more round track cars.
