454 engine

Re: 454 engine
 

Is the 454 injected or carbed?

Is the current 3 speed auto or manual?

Some other stuff you may not have thought of: radiator, driveshaft, various linkages & of course motor mounts.

I haven't done a swap like this, but lot's of members have.

We're gonna need more info to help.

its carb,with a manual three speed.but im changing to automatic floor shifter.so i gota change drive shafts too.im adding power sterring,new radiator.and im going with a comp cam a 230/230 @50 with a edelbrok air gap.and a holley 750.what u guys think about that combo?

Re: 454 engine
 

With the exception of the cam, that's the engine I put in mine. I started with a 350 though. The cam I'm using is a Xtreme Energy 552/550 286 dur. I had the heads opened up with 2.190's / 1.880's too... It's a nasty combo, sounds great. Of course, I put all MSD on it, electric fan, 700R4. Don't know how accurate but Desktop Dyno says 451hp/502ft lbs @ 5500. Workin' on Bags now before I put it back on the road.

so u think its a good combination or not? what u guys think of the cam? should i get a different one.i want power and something that sounds good.is that cam fine?

Re: 454 engine
 

As far as the engine.. depending on how you want it to perform, you can build it like you have it or pump it up a bit. Mine is just mild. www.compams.com has a section where you can listen to their cams.
