431rwhp/386rwtq - TEA LT1 heads/custom TR cam We just finished my girlfriend's car last week and were very pleased with the numbers it put out.
The plan was to do the heads/cam over the course of a weekend, but once the stock cam was removed, the front cam bearing showed a ton of wear. We pulled the motor and found nearly all the bearings in the motor were showing copper. I was pretty surprised given the relatively low miles (66k).
Anyways, here is the mod list:
Rebuilt LT1
- Stock pistons, rods, cranks
- Total Seal rings
- Clevite main bearings, King rod bearings, coated Durabond cam bearings
- ARP rod bolts
- Melling HV pump
- Canton pan
-Total Engine Airflow (TEA) ported stage 2 LT1 castings (2.00/1.56 Manley valves) ~ 11.0:1 compression ratio; heads flowed ~ 265/200 at peak on Thunder's bench
- Thunder Racing 234/248 .608/.576 110lsa (110ICL) hydraulic roller
- Crane 99893 valvesprings w/ Ti. retainers
- Comp 1.6 rockers (7/16" studs)
- GM guideplates
- FMS 7.350" pushrods
- Morel lifters
- FMS ported LT1 intake manifold
The car is a '95 Z28 6-speeed with Hooker longtubes w/ no cats, Hooker catback, CSI elec. water pump, AS&M 58mm TB, MSD 6A and coil, Dynapark opti, SVO 30lb inj, Racetronix fuel pump, LS1 alum. driveshaft, stock rear w/ 4:10s.
Final #s were: 431rwhp/386rwtq through full exhaust! Not bad for LT1 heads/intake!

Needless to say, it is a night and day difference from her bolt-on setup! Huge thanks to everyone involved in getting Nat's car back up and running and Brian @ TEA for a killer set of heads!

It was just a super budget rebuild and wasn't planned. We didn't want to dump a ton of money into this motor as we will be starting a 383 buildup this summer.

i did something very similar, but did not do heads, its easier to say "why didnt you do the bottom end" when really if you want to do that right its going to pretty much double your spenging.
Must be a great girlfriend

Did anyone happen to get a killer deal on some LT4 castings around Nov 2004?
Congrats on the power Jason, looks like you put together a killer combo

Thanks everyone, it is just nice to have the car back on the road!! 
The LT1 pistons already have valve reliefs and the cam cleared just fine. We used a .026" thick gasket from Mr. Gasket.
