the 454 block with a 366/427 crank would be a good way to fly i know guy that have run in the 11s with the chevy II with about this size engine but you want to run pump gas i would build a flat top 468 454 pistons are EZ to find and better on price
well a bottle of octane boost wouldnt burn my spirits either :LOL: well when you put a 366 crank in a 454 whats that turn it into ? man i really need to do my homework, hey at least im willing to listenQuote:

Pat,I was looking at the old PBM catalog.
I think you can build a 496 for about $50 more than a 454.
How long do you think a set of hyper. pistons will last in a low 11 sec. car??
If Scooter had said low 12 sec. car I would say run the hypers. but in a low 11 sec. I am having my doubts.
bore is 4.250 454 block or 427. and any crank 366/427 is 3.760 crank will make a 427 you need 427 pistons and any big block rod for a low buck build would be a stock 6.135 long rodQuote:

i would say away from the KB for this build i feel better with the speed pro s or a srp pistonQuote:

yes it will see some race useage bu tlike i said be more like 60 % street 40% race and remember 500 mile road trips or more:D
I have seen to many of the KB pistons just lift the tops off just above the top ring land.Quote:

so it can be done for 3500 or less, thats awesome.
I would say it can be done for $3,500 with a solid lift cam but if you go mech. roller or hyd. roller or add the SRP pistons I would say you would be closer to $3,800 and as much as $4,000.Quote:

just a good build to pop off low 12's mid 11's would be perfectly fine. id run a solid cam yes. because it still ahs to be somewhat streetable to drive from spokane to the coast :D
now ive just gotta learn to not buzz them 7500? :LOL:
Yes,I am thinking more like 6,200 to 6,300 rpms.Quote:

Yes,using a 3.73 gear and a 4-speed with a 496 low deck,solid lift cam, a low 12 sec. pass is done very easily if you can get enough traction.Quote:

fenderwell headers anyway :D clearance for the motor and exhaust will not be a problem at all either. now what about the hipo 396 wasnt there a 425 horse version :D
I was thinking more like a 550 hp solid lift cam 496.Quote:

You could use a set of full prepped stock 6.135 with the ARP rod bolt if you wanted to.Quote:

would those speed pros stand up? or do i need to look at je/srp's
I.M.O.,at 12 sec. you should be o.k., but in the low 11 sec. area it would bother me.Quote:

I think you should be able to run on pump gas with-out adding any type of octane booster.Quote:

Yes,you could with the 496.Quote:

ah you went and spoiled my fun, :D
Yes,I can be like that.:LOL:Quote:

I think you would loose hp/torque and have driveabilty problems.Quote:

Yes,but at 6,300 rpms and less I don't think you would gain anything.Quote:

with a small car it would help to dump some TQ he will get out of the hole better and i have ran the T rams on the street with small CFM AFBs on them they work good and it will make more power over a single plane with re work gm rods with ARP or SPS bolts have seen them go past 6800 rpm and a stock cast crank low piston weight and a good valve train with the right bottom and clearance it will run just fineQuote:

damn , yall cant get 11's out of an iron headed bbc? thought some of the bad boys did that in the 60's ? :LOL:
