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 CR; 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!

I don't have the graph scanned, but I will get to that this week. The #s are SAE corrected and the car pulls to 7k easily.

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!

Dang, I bet that baby gets movin nicely

 

 

Great numbers! I cant wait to get my TEA ported TFS head motor running. Brian does great work and builds a killer set of heads.

I got a set of fully CNC TFS heads from him. 220cc heads, they flowed 317cfm @ .700. With my SR 355 I hope to put down over 450 thru my auto.

 

Very nice numbers.

 

Are those cam specs correct or is that a typo, a 14 degree split on intake/exhaust is pretty big.

 

Awesome #s!!! You guys do good work.

Also, I can't wait to see if all the AI & LE bandwagon camp nutthuggers decide to give you props or mount the usual H&C attack replies

 

The cam specs are correct!

Thanks for the congrats, everyone!

 

and you built this for a girl?

 

I was thinking the same thing. Also, I never knew TR made cams for the LT1. Custom?

 

Nice numbers: don't imagine that she will be using it to grocery shop.

 

Awesome #'s

 

Anyone that "builds" custom cams usually just figures out the specs and then gets them ground somewhere else. I can't remember who Thunder uses, but they understand what it takes to make power in any SBC or BBC.

 

Excellent numbers

Is your girlfriend going to be racing this car?

 

maybe Comp, but probably CamMotion
