Hey guys, I'm trying to put together my very first engine and I figured you guys could give me some input or comments on the parts combination.

I intend to run mostly on the street. I intend on using my current TH350 trans w/ 2400 stall until I can find either a TH 400 or a good 4 speed manual transmission.

454 30 over MK IV Block
118cc Heads casting #14092360 (Ported and Polished, 3 angle valve job,Comp Cams Magnum 1.72 rr)
Keith Black .250 Pop Top Pistons (10.2:1 CR with 118cc heads) with Gapless TotalSeal rings
Comp Magnum Muscle Solid lifter cam (280/285 adv dur,242/250 dur @ .050, .575 intake and .604 exhaust lift, 110 LSA)
Edelbrock RPM Air Gap Intake Manifold
Hedman headers with 1 5/8 tubes

I was wondering if this sounds like an alright combo ? Especially since these heads are the small oval type off an 87 truck, but they are ported on the openings to match a regular oval gasket and intake manifold. Any ideas as to what my HP and torque would be?? Any comments are appreciated....Thanks guys

1 5/8" headers??? smallblock headers on a big block? and peanut port heads...might ought to rethink that part of it. 1.75" headers,and I'd get some large oval port heads.

I agree with Bob, this engine needs to breathe graemlins/thumbsup.gif

The heads that you have,are they large ovals or are they the peanut port type?

According to the MorTec website they are listed as 86-88 truck heads. If that is the case, they be abit "small" for a 454 with that cam. IMO, those heads (on a 454) would be done by 5500rpm and the cam looks like it would make power to 6300-6500.

They would probably make killer torque down low and in the midrange, but would limit higher rpm power.

They're the small peanut port type :( I guess I should go with a better set of heads then and some 2 inch headers. If I do that, what do you guys think of this combo? I want something that will be awesome on the street and fun on the strip. I've read every single article I can find but I just figured that you guys could give me some better input since most members have hands-on experience with this kind of stuff.

If I make those changes does anyone have any guesses as to what my HP and torque would be?
