thats a 557 on pump gas

Thats insane dude, you must have put some bigtime hours into those heads to get them to flow that much without any PA

myshifter

they were maxed out, hit water jackets a few times and then welded them. Thats when TFS sent out a batch of heads that had wacked valve angles, needless to say it blew up shortly after due to TFS's screwup

88BlueGT

Wow... thats crazy! hp/tq? what car? 1/4?

myshifter

I dont remember the exact numbers but I know it didnt crack 600hp, it was 10 years and 20 engines ago. It never got to the track, it was a street engine that blew up in a few weeks. It was in a 95GT.

88BlueGT

Im suprised you didnt hit the 600 mark. Anyway, do you have any plans of building another BB?

myshifter

Thats all I build now are big blocks. 600 inch C460 headed motor is next

PX429

So what can you do for my 429?

P Zero

I'm right around 350hp or so. I guaged this by racing cobras. Except for the supercharged ones I leave cobras pretty hard, as in I get on it in first let off the gas until they catch up nail second pull a couple of car lengths back off the gas again, let em catch up then nail it again. Im not planning on goin to the dyno cuz I dont really care what the exact HP figure is, plus it costs money that otherwise Id put into the car somewhere else.
-P.
PS: I have a new motor in the works for my 5.0 ranger........twin turbo. Supposedly it should make 1000hp.....we'll see.
