I had a 454 stroked to 496 with a Eagle kit. The compression is close
to 9.7 to 1. The cam is a Comp Cams hyd roller 11-450-8. Edelbrock
RPMs. A 800 cfm Edelbrook AFB. The engine is smooth, has good vacuum,
and has unbelievable torque and power.

Hey everyone,
Well for the last few months my Chevelle has been backfiring and
running like crap. I finally figured out what the deal was
yesterday....The exhaust valve on #8 is burnt. The motor is old and
tired. So I'm going to rebuild it.
So any idea's for engine combo's? I don't have a bunch of money to
spend on this but I would like to bump up the performance of it. Right
now it's a really stock 454, 8:1 compression. I'm thinking about
bumping up the compression to 9:1, adding a cam, and if I can afford
them, maybe some aluminum heads. I think that would really waken up
this motor. But basically this is a street car that's cruised 99.9% of
the time. So I want the drive-ability.
Anybody else care to chime in?
Thanks!
-Tim
