Doober,
Monster torque. All i can see are the lift figures. What are the duration and lobe sep and installed c/l?
This motor would be great for DD of any type: s10, g body (insert rear wheel drive gm car here)
My bad, I didn't make the window big enough for all the cam specs #-o It's a Comp 12-407-8 (PN is at the top, XR252HR I believe is the grind). 206º/210º @ .050", .472"/.480" w/ 1.5 rockers, 110º LSA. Powerband is advertised 600-4,600, I'm debating on stepping it up a hair, try to carry the torque out a little farther & bump up the HP. After some more prodding in Dyno2003, I found this one... average torque is still around the same, but peak HP is up by 30 or so (close to 380).
I also picked up the throttle body yesterday. It's mounted to what I'm pretty sure is a factory TBI-to-spreadbore adapter... so if I really wanted to I could try to find an aftermarket spreadbore intake with an EGR valve... it should flow better than the stock intake, but since RPMs won't really go past 5,000 anyway I'm not sure if I'll even bother.
Not bad for $100 8) I dare you to find one for that price on eBay (not a 4.3, 305 or 350 one either)
