Hey guys just have a few questions . I have an lt1 ported heads w/larger valves (2.00, 1.56) 1.6 rockers, jet hot long tubes with high flow catts into a gmmg with the gm847 cam. Forged bottom which I believe is a 355. All of this running through a 4l80e, yes the 80e not the 60e
and the Dana 60. Oh and the mallory ignition box. So currently I put down 350 HP 300tq to the wheels. Redline was set at 6500. I can adjust redline with the Mallory.
Even with the 4l80e and Dana 60 I feel these numbers may still be a little low. So my questions are,
1.) The cam was all top end above 4k, is 6500 red line way to low for this cam? I hear it pulls in upwards of 7200rpm
2.) If my redline is too low what kind of gains will I see from a few 100 rpms
3.) Stock throttle body is suppose to be ported to a 52mm if it is not is this affecting me in anyway and if so should I just go aftermarket 52mm or 58mm?
With this setup t56 users are putting down around 400-420 wheel and 4l60e's usually 380-390 maybe. Its very similar to the LE2 setup. In all honestly with my tranny even 370 would satisfy me.
In advance I apologize for grammatical errors and/or spelling errors at almost 3am and all typed on my smart phone lol.
