What really matters is 1/4 ET...

It runs 12s at 7000' DA, according the people who move up here, that would be 11's at sea level...All motor.

my r/t flow #s are just shy of yours

EDIT: wait, are we talking RWHP? the cams pretty stout, did you check it out? it is a hydraulic roller, the blank before grind was however solid roller. fully compressed spring pressure is 390lbs
Yep RWHP. My Dyno numbers I posted was with a lot smaller cam than I have now...I'd get it on a dyno, but I don't realy care what it makes....LOL

These are 1.92 flow numbers from Ryan Johnson's site. Shady Dell Speedshop.

LIFT-----ASCAST--------PORTED
---------IN/EX----------IN/EX
.200"--135.6/110.4---148.4/111.8
.300"--194.9/154.9---208.7/155.3
.400"--227.4/173.5---243.2/189.1
.450"--233.9/177.3---252.5/194.6
.500"--239.4/179.4---255.6/197.7
.550"--244.9/180.8---259.1/199.8
.600"--245.0/181.8---268.4/201.2
.650"--245.0/181.8---276.0/203.2
.700"--241.5/183.2---281.2/203.2

All #’s at 28” of Water
1.92”/1.625” MP 8MM Valves


Comparing numbers from different benches is like apples to oranges, but I think your heads will be just fine...You got a killer deal on the motor...

Not sure which one you got, but I have never been a fan of the lever type unless it's a really expensive one that you can only use with the heads off. I prefer the ones you have to screw down all the way, so you can hold the jaws on the spring while tightening. They work better for a heads-on removal than the lever type heads-on model, more room to work in the engine bay.

one like this works just fine for me:

just dropped it off

he felt it and looked at it and he said most likely by the time he got a good finish he would probably be .003-.005 into it (no pits, corrosion). so +.010 will likely be what he has to do. he said hell put a gauge on it and make sure though. he was a little heated that someone allowed his fresh engine to sit out in the elements and get corroded.

i left the entire bottom end with him so he can mock it up and press the new .040 KB's onto the rods. although id like to hear a hone will do (he said he didnt think boring it would be necessary at first, but then i showed it to him and he changed his mind) but if boring is necessary, i guess its worth it.

didn't you mention something about 500 bucks for pistons and such?

Could I talk you into total seal piston rings? (no ring gap.)
