Ok. My mind was made up to just do another small block for my Chevelle when a buddy told me he has a 454 from a mid 70s truck. He said it is a standard bore that's in real good shape he also has he thinks standard bore TRW forgedpistons,rings,bearings,oil pump,and gasket set new in boxes. He said the pistons may be .30 over but pretty sure they are standard. I could get all of it for around $800 the motor is complete with stock heads,HEI,and oil pan that I would also need
If I put it together with some aluminum heads,solid flat tappet, RPM intake and a nice converter how do you think it would run? How about with a 150 shot? It will be in a 67 Chevelle full weight with 3.73gears the car also has UMI control arms,Comp.Eng.drag shocks,airbag in the rear, and will be on M/T D/Rs or ET streets. Thanks

it'll run as good as the heads/cam you pick will support. BBC are proven motors. It's fairly easy to get good hp out of them, and a matching tq curve that starts down low. You probably should figure out what alum heads and cam you want to run in order for the guys on here to "tell you how it will run"...
