Thread: All out 327 build

Tweet

Okay so i picked up a 1968 327 the other day and i was wondering what would be a sweet build. I have an idea of what to do but i would like to see some suggestions. I have plenty of money to spare on the motor and i was thinking about boring it to a 331 with 11/1 or 12/1 compression and aluminum heads etc..... The car is ganna come in at around 2700 pounds and i would like to at least pull a high 11. We wil rarely street the car mostly strip car. So what do i have to do to accomplish this. Will i reach my goal with a build like this?

First check the date code on front pad to be sure it did not come out of somthing like a vette, it might be worth more to someone looking for a #s matching block.
If its not anything fancy you have to copletely disasemble the engine and throw everything away except the block.
You now have a 350 or 327 block and you just buy whatever parts you want. Waste of money to build a large journal 327 you need everything new. I am building a small journal but, it has a steel crank already.
For the same money you can build a 350 or for a little more a 383.

For a 90% strip car I think the best thing is to make that 327 a 383 stroker engine . This is a for sure way of getting your car in to the 11s . Or better yet save the 327 for a street car . Then pick up a 350 4 bolt main block that will be stronger for the 383 stroker build . But for heads I always liked Brodix . Go with a set of Brodix Track 1 221cc intake run 67cc 2.08 in/1.60ex valves . For the intake run a Edelbrock Victor JR with a Holley 850 race D/P carb . For a cam you will need one thats 235to240 dur at 050 with a lift of 525 to 550 and a 108 lobe sep . Some will say go with a bigger cam . But I think a max of 550 lift will get your car in the 11s . And the valve train will last longer then a larger cam .

it never fails, nobody can ever tell you how to build it up, unless its a 350 or 383,

Da Grump built some pretty potent 331s.................

blower/supercharger/turbos ,otherwise ,its about 400 to 450 hp at 9000 rpm depending on if it stays together.
Forged crank ,forged rods,forged pistons,good heads and some sort of huffer on the top 6oo to 800 hp.....a little sniff of n2o and you could hit 1000 hp..........of course this is a 20 to 30 thousand dollar engine,not sure if thats in the budgett or not.
350 375 hp is more in line with what this engine will produce, max normal effort,anything more and you are straight out wasting money and fighting for every last hp.

sure you can bore out that 327 to a 331 run 12.5 to1 forged pistons with full floating pins . Forged crank with 4 bolt angled cap with ARP stud kit . x-rayed sonic tested H Beam rods . 600 + lift roller cam roller rockers with stud girdles . With Brodix SPX heads 245cc intake 2.140/160 valves . And a super victor intake with a 950 DP Holley . Then for the trans set up PG with a 1.82 ratio and brake with a 5200 stall and a 5.13 ford 9in rear end . This is the hard way . For what it will cost to make that 327 run 11s you can build a 350 and a 383 that can do the same easyer .

go small for once .. dennis mitchell .. many many time national record holder in several classes would destroke his engines to under 270 cubes then spin them up in liteweight cars to 13 thousand rpms .. what a show he put on

This gasser was at the show Sunday and runs a 301 Chevy. The info board on it said it is running 6:48 gears. Can you imagine the R's he is buzzing in the lights?????

I ran a little 301 in an altered in the early '70's, turned 7 at the end with 5:13's, so I can only imagine what he is turning. But that is the beauty of these little motors, they live at high rpms.

Oh No, not again!!!

I am gunna leave the 13000 rpm debate alone .....
But I will point out that the highest certified sfi rating on parts is 10000 rpm,anything over that and its a no go on any type of guide lines , basically no one can tell you when it will puke out the flywheel or the dampner may fly apart ,because the rating only goes to 10000 .
I cant even imagine what a small block flywheel would do at 13000 rpm when it broke apart ,much less 10000 rpm.
My guess would be if they could spin up a dampner or a flywheel on a test machine to 20000 rpm ,even though it is not reality to rev a engine there,they would use that as a sales tactic and all dampners and flywheels would be marked at the highest possible rpm for sales and marketting purposes.
They only say 10000 rpm ,which leads me to believe much more than that and its comin apart,not if ,but when......

that s&s willys is one of my favorite cars of all time

I had a 302 Chevy that had a clutch disc explode at 10,500 it took the pressure plate completly off the flywheel. Then it took the scatter sheild and block plate off the back of the block, and broke the front bearing retainer on a Nash 5 spd. Solid motor mounts and the steel cable kept it up and off the track. All the safety stuff worked but what a mess.
