1974 Trans Am 400 rebuild engine

[MrJABER1976]

what is the best carburetor it sho'd fitted for 400 1970 trans engine ?

@MrJABER1976 Hmmm, I'm using a Holley 4160, 750cfm and it's awesome. But I'm not using the stock manifold, I'm using and Edelbrock Performer (the performer rpm is too tall and you'll have problems with the scoop clearance )

awsome motor! Im just finishing my rev demon! its a 350 pontiac with 455 H.O heads and high top pistons. should pull 8,000 rpm and around 400 hp =D

[fabioaro]

@AndersonRacing44 wow! that's gotta be really something!! please tell me when you finish it and have some video available!

nice i had a 70 it was a torque monster.. they dont like 2 rev much though.peace.

[fabioaro]

@philthyco awesome pal! the 70 model is a dream one...

[philthyco]

@fabioaro thanks my bud has a 74 that we just built also..how how does yours rev?

[fabioaro]

@philthyco hey man, it's all stock internal, it's revving up to 5600-5700rpm...

[philthyco]

@fabioaro some peple say they can rev over 7000rpm stock ..i said heck no!

[fabioaro]

@philthyco no no, you can see the engine is already loosing power when getting near 5500rpm, you could rev more than that with other cam, but then the rest of the internals wouldn't last long...

[philthyco]

@fabioaro yea i didnt think they would rev higher then 5500 rpm..nice motor by the way...

Wow. That thing is amazing!! It sounds like you need to take some shims out of the starter though. Great Job!!!!
