Thread: Official 4V Naturally Aspirated HP/TQ List

Numbers updated. Go to mach1registry for auto numbers. Some Machs came with automatics.

hey just noticed im still on the "front page" with my old 320 number. update- 330/327 SAE RWHP/RWTQ. well past the break in- and still using shell rotella. mainly because its cheap and synthetics = 5bhp. not worth the cost to me right now. working on a short runner intake NOW for it. just give me time. and just curious- WHO out there is running a auto trans besides me?

The problem is that you are kinda mismatched. That intake needs to be cut and the runners shortened. I bet that would free up alot of power. It will not kill your low end. It may be less than you have now, but this isn't a big low end torque motor to begin with. I still can't figure out why people even talk about low end torque with a puny 281 ci.
