Thread: not new to the site but new to 454's

Tweet

Hey guys,

Ive been reading up on this site for several months now. So I said heck with it and finally registered.

I am the proud new owner of a 454 w/ a 400 turbo tranny. This summer, I bought an old 79 scottsdale 3/4 ton for 300 bucks. pulled the motor and tranny. kept some other things off the truck like the radiator and rear, junked the truck and got 200 bucks. so i got all that for a 100 bucks

My buddy has some spair parts and we plan on doing a rebuild. the motor will be put in a mud bog truck.

heres what were going to do...

.60 over bore (friend owns a machine shop w/bore). free!
rings. speedpro or total seal
wiseco forged flattop pistons. free!
steel rods. free!
cam (unsure of specs as of now. maybe someone can help me)
750 cfm edelbrock. free!
edelbrock performer intake. ebay
stock oval port heads
cheap set of summit headers
I'll probably buy the full MSD ignition kit for electrical. jegs

we may or may not puta small shot of no2 on her. thats still up in the air


welp thats going to be my setup. does it sound okay? I plan on turning around 5500 rpmz. with all that said how much hp/torque do u think i can make with this?

Any and all advice is greatly appreciated

thanks,

Ross

ps. the pistons, rods, and carb are used, but in good shape. they have been donated. keep in mind Im on a poor mans budget

will somebody talk to me? Im not a troll.

Wheres Mr.McCarthy when you need him

To give an informed answer, more info is needed.

If the heads have a 118CC chamber, the flat top pistons won't give much compression (8 or 8 1/2-1). If you plan to use nitrous, the cam choice will be altered somewhat. Torque will be more important in a Mudder than HP. Tell us what you want to achieve, and we can supply lots of suggestions.

HMMMMMM..... realistically, my ultimate goal is to use the parts I have to make a dependable motor, that will start when I turn the key over. have a nice choppy cam. and just be a good strong motor.

Your right, torgue is the key. Im running 72 inch tractor tires. the motor and tranny will bolt up to a gear to gear divorced transfer case out of a combine. you can actually move the truck by turning the input shaft with your hand. so yes, it is geared verry low

Im on an extremely tight budget (as I am learning, building a big block is not the cheapest project out there) so i really want to use the parts that have been given.

these are 118cc heads

thanks for the reply geezer, check your pm's

ok i see what your doing i do not have much to add. the deal were big blocks cost alot is B.S you can make more power and put more power thru stock parts if put together right then most all engines .so for the dollar there one of the best bangs for the buck. if you need to pick up cans. sell scrap. get another job.do some horse trading .shop on e bay .swap meets and get smaller cc chamber heads or pistons with some domes. or get it has good as you can marine cam will do for now 500/500 222/234. 114 or some were about there o deck the block .and you can chop some off the heads if you going to use all your stuff

I'd start with a hydraukic cam (do to $$$$ considerations) or if in the budget a hydraulic roller, with somewhere around 230/238 @ .050 with a .575 or thereabouts lift, mill the heads to about 112 CC's and run a dual plane intake.

It's a starting point and should perform well with or without the nitrous.

roller is were i would go. just happen to have a new one for sale 4/7 swap steel core .this cam can make good power 238/246 627/627 112 but you shoud have abit more cr. if no money the first cam hyd flat will make very good power use a dual plane is well . we have used some of them . but hard to say if it will live thru break in thats why i use roller cams on bbc
