good motor?

i have this 454 that i built about three years ago just sitting on the engine stand, and i'm thinking a may put it and my rebuilt TH400 in my 65 chevy SWB.
from what i remember i spent about $4500 on it and the trans together.
i was wondering if i made a good investment or not and if there was anything special about the block or heads, and/or something i might not want to know about them.

heads/ 73-85 oval open 454 118cc chamber, 256/114cc ports
(#336781/A1774/GM10T/PASS) with 1.7 alum rollers

block/ 72-79 454 2-BOLT (#B2074/GMT12/3999289 P) with stock crank, 11.1 pistons, and mild RV cam (not sure of lift and duration)

carb/ holley 850 double pumper with shaved choke, K&N

intake/ edelbrock RPM performer air gap

other/ HEI dis, hooker headers, MSD 8mm wires, delco starter, 100 amp chrome alt, weiland high flow alum water pump, and new stock hormonic(?) balancer.

trans/TH400 built by a pro speed shop, suppost to handle 400 plus HP, street/strip shift kit, 2500--2800 stall
(i don't know a damn thing about transmissions)

P.S. just off the top of your head, what kind of HP you think i have?


oh yeh, they both came out of a 1974 chevy 3/4 ton suburban.

and the block is 0.030 over.

Pretty good street combo you got there, except the compression, you`ll have to run race gas to keep it out of detonation, the heads are the itermediate heads from what I gather, they`ll work nicely with the cam you chose.
Desktop dyno shows a ball park figure of about 375 horses and 470 ft lbs of torque, a real stump puller.

Could you also give me an estimate??

SBC 350 to 355: TRW 12:1 forged, Ported 492 angle plug heads, 2.02/1.60's. Hooker super Comp 1 7/8 headers, Victor JR intake 750 holley, 560/580 lift cam 258/268 duration and 106 seperation. I think that's basically everything.

howziit guy!

good motor!

all it needs is a moderate cam(comp XE274H) or equivalent, less compression...and you're looking at REAL HP/TQ, on pump gas!
