Am changing things up a little, adding a tpis 102 tb, 3" exhaust .
My setup is 402 ,afr cathedral port heads.
I have an 8" powerbond OD harmonic, 3.3" snout, and overdrive cogs.
I also have a 1 gallon moroso coolant tank, and a fluidyne heat exchanger with a fan.
The dyno was 650/650
The cam was spec`d by the builder, and it has a fair bit of overlap, 17*
I wanted this motor to be able to rev, 7200rpm, to save a gear change, 4th-5th, now am having second thoughts. If I calculate my blower speed like this 8"/3.3 x 1.2 x7200 =20945 rpm.
But I would like to pulley down, so do I lower my shift rpm`s? e.g.......
3" pulley 8/3x1.2x6600= 21120 rpm ?
How are some of you using such small snout pulleys ?
I know my cam might be a bit of an issue, but it`s stayin in for now, have read many pro`s and con`s to overlap
welcome all comments
here is cam card :
