[454C10]

check out this 454 build.

http://www.superchevy.com/technical/...ild/index.html

565hp with 8.25:1 cr, cheapo summit flat tappet hydro cam and stock pistons.

Then 736hp with a little 150hp shot of NO2.

all for $2500.


You don't need that big a cam or that much compression. 9.8:1 is enough for a 454 and a cam with around 250 degrees duration at 0.050" lift. Should be able to make more hp than you can stick down on the ground.

that with a 3500 stall, 4.11 gears, in a lighten nova should get you easily in the low 11's at 120mph

good luck with those heads. i would be using a stud girdle also , I had same problem I removed a little of the heads so sparkplug would clear. with a .640 lift flat tappet no girdle broke the stud boss out of the head the casting looks very porus on the inside and these heads are around 5lbs lighter than any other al. head. Just fired mine up today with a set of steel 188's no more procomp for me . there combustion chamber is different than stock is why you hit.

we are using a stud girdle it is recommended to use one with my cam, The castings were the only part or the pro comp heads he was ok with using he also said the assembly was very poor and would not have worked with even a smaller cam. I would never buy another set I traded a better set of heads for them I had a set of 69 427/454 rectangle port aluminum heads that needed valves I traded for this set

Tonka- an option is to sell the PC's on ebay and buy yourself a set of Profilers.

Well my motor is done and I cant wait to get it in the car I ended up spending a lot more money than I planed but I think the end result will be worth it so what we have now is block was All re machined converted to 4bolt main 60over
JE pistons eagle rods all rebalanced Heads were all re machined for new valves springs retainers ect I had him assemble the whole thing I need to go get some valve covers and a low alt. mount a set off flex plate bolts and converter bolts and she is ready I think I may have to sneak off to the parts store before my wife gets up
