.020 over LT1 block, notched + extras
Also gonna sell my old stroker block. Everything looks good, also going to include the SCAT crank (3.75" stroke), GTP 6 cam (approximately a CC306 equivalent), GMPP Extreme Duty timing set. I pulled the motor due to a fluctuation in the oil pressure (would drop to ~20 psi under heavy acceleration then immediately return to normal), so you'll want to have a machine shop check out whatever you reuse. It was still running good when removed, but I didn't want to frag something a 100 miles down the road. It's been setting in my garage >3 years.
For local pickup in Pipe Creek texas only (NW of San Antonio).
PM me with an offer.

Regarding the inevitable questions about the oil pressure, here's what I know (which isn't a lot)...
I'm thinking it was likely a main or cam bearing, but it was >3 years ago. I missed a gear, then the next time I got into the throttle the problem started.
The oil pressure would drop from whatever it was normally (it's been a while, sorry) to about half its normal value, then it would immediately return to normal (this occurred over the course of about half of a second). This symptom was repeatable and always occurred near the same rpm, which happened to be near its peak torque rpm. I pulled it before anything drastic happened; car ran fine and made no weird noises and displayed no symptoms other than what the oil pressure gauge said; it still made full power, etc... I haven't looked at the cam, but the crank looked fine (no visible abrasion on the crank at the mains, etc), however the mains themselves showed a little brass, I believe (I'm no expert in that area, but I don't think they should've looked like they did).
The motor has been stored in a garage since it's been pulled.
It was the only time I'd missed a gear in the life of the motor, and supposedly it was built right
(tho the crank was cheap, I guess).
I'll shoot some pics and get them up in about a few days (if it's not already sold).
