The ProCharger and matching camshaft:





ProCharger sent a nice hat with the kit, but I think it is a bit small for me.

The heads arriving. I have already run these on my old nitrous setup, so more pics to come when they are cleaned up again. The Dart Pro1 LS3 heads are excellent to start with, but even these great heads picked up nearly 3 MPH in the 1/8 mile when Frankenstein reworked them. Amazing.

Good catch. It looks like I screwed that one up when I had it ground I guess I will have to regrind that exhaust lobe.

Steve,
Congrats on the new combo, way to step up!
Looking forward to results.
Will you be able to post Flow#s on your Heads?

speedtigger

iTrader: (16)

Yeah, if it tries to go that fast, I will turn it down. I don't want to go that fast in this chassis. That is one of the reasons it has the F1a94 and not the F1x.

They were never flowed. I don't know if Frankenstein has flow numbers for this head program or not, I would have to ask.

Rock hard over the blow through, though I have yet to achieve completion like A.R. did.

Do you drive this thing on the street still?

speedtigger

iTrader: (16)

Absolutely! It is primarily a street car. If I were to have a racecar, I would use something light! LOL. When it is on the road, I drive it about 2-3 times a week. I love driving it. It has overdrive, full interior with factory console and seats, power steering etc.

Here are some pix before the 6-point and the Welds:
