My first top-end “Craigslist” build (build sheet and dyno results)
Finally finished my Craigslist top-end build project – Took a lot longer than I thought because I travel a lot and my tuner wanted me to make several other mods before the dyno tune. The last mod (Felpro 255 fuel pump) was completed on 7/7/13 and the dyno tune was done on 7/12/13 by Tad Banzuelo in Placentia CA. Built sheet and dyno results are noted below.
Going into this project these were my goals:
• 300 + hp at the wheels
• Fix oil leaks in the front of the motor
• Pass CA smog
• Keep daily driver / weekend cruiser quality
• Do it on the cheap (buy new where I need to)
Results:
• 300 + hp at the wheels – 332hp
• Fix oil leaks in the front of the motor (Fail – I think I screwed up the H2O pump seal)
• Pass CA smog (Tad says it will – will know in December)
• Keep daily driver / weekend cruiser quality - Yep
• Do it on the cheap – Sort of (ended up buying injectors, 52MM TB, Fuel pump, and different plugs for the tune)
Dyno Results:
Tad said that my set up is being held way back by my “Y” pipe and the OEM single cat. I am happy with the results considering the restrictions I have to live under. It would be nice to run long tube headers – it sucks having to live under the CA smog rules.

Wow those parts costs add up fast.
Nice torque curve, too bad you have to abide by CA smog laws. I'm guessing the y-pipe and cat is why torque starts to fall off just past 5k.
How does it feel to drive? Are you happy with it?

Wow! Thats nice to know info. I'm in the same situation and have to add not only are the CA smog rules limiting performance but a California mortgage digs deep into the budget. It takes a long time to sort things out and keep costs down. Like my Headman Headers came with welded plate on the tube but no CARB number - just the company name. I really liked those headers as they fit great but they had to go - Summit actually let me exchange for legal Edelbrocks. But problem is there are only shorty headers that are smog legal in CA.
So look over your list for someone if they were to "do it again" to save a few bucks.
Lets take out unneeded expenses and parts.
lifters = $122
water pump = $54
fuel filter (normal replaced part) = $14
Bored out TB = $178
Fuel Injectors = $90
fuel pump = $127
normally reuse crank hub = $109
air check vlvs = $28
O2 sensors = $50
AIR check vlvs = $28
Dyno tune not necessary $450 - $200 for mail-order tune = $250
Total = $1050
This is assuming fuel pump, water pump, opti, o2 sensors, air check vlvs not needed though nice time to replace.
So $3277 - $1050 = $2,227
Thats 'bout cheap as it gets for a top end rebuild for any kind of performance improvements. But when u consider the engine life should be extended its more like preventive maintenance that adds a fun factor to driving it.
Thx for the report,

Nice results! Ive been looking for a local tuner for our ol lt1s as I think theres alot left in my mailorder tune. How was your experience with tad? Thats pretty local to me I may have to go down there and talk to them...

I really like Tad and the work he does. He has been working LT-1s for years. He still has (at least) two LT-1 Impalas and his Dad has one also. He tunes everthing but is was good to find a tuner that knows and would do my OBD1 LT.
