I think it would be great Ty. I dont think I will be able to spend on the old cars but that is really because I already spend to much because I have TOO many cars and the payment on the LSS. I like your attitude on this keeping guys interested in the older cars by producing some aftermarket. Everyone wants to do the L67 transplant but thats almost getting boring and I am a fan of the L67 and know it would be great in my old 86 but then what about those beautiful early LN7,LG2,LG3 engines. Oh how I would like to see a few of them out there kickin butt.

I've hoped for the time to do port matched and polished heads and intake w/TB with a core return for a good price with good gains like the Olds V8 community has. That would be bolt on performance. Maybe some compression gains in the heads also if it could work ? Larger valves or rocker ratio ? Why no compitition cams ? How about a better rear bank exhaust pipes. I believe the LN7 pistons could be put in the 87 LG3 to boost comp to 9 to 1 but just dont have the time to play engines now. Just 200 ponies in the older 33-3400 lb cars would make them move quite nicely. I just dont see much more than 200 NA possible on pump gas road car. You gotta figure the much refined L36 only goes 205. The hot air turbo Regals were 215 while the 84/85 Riv was 210 with its different torque camshaft.

Turbo - I think a reliable 250 HP on the old off center 86/87 engines may be able to live if they dont lean out or over rev. I believe the crankshafts in any of the "corporate" engines even the 88+ "on center" would be the weak link. RPM'* must be kept down. Even the Turbo Regal guys keep the r'* down. The stage two guys were having billet cranks made because the old stock is getting thin. The Turbo Regals have the crank and rods to survive while the corporate V6 cranks were built for 150-170 @ 5200 and are camed and breathed to die out at 4800 anyhow. So I feel RPMs must be kept down and we need to think torque. 380 ft.lbs would be awsome. Can the crank take the hit ?

3-400 HP on any of these engines ? forgetaboutit ! One early experimenter dynoed 500 before he launched the crank but that gives no indication of what would survive 3-4 years on the street let alone one.

92Trofeo - yes indeed the Riviera, Toronado and Reatta actually weigh more than the H bodys. Why ? Darned if I know. I'd like to put them on a scale to find the truth. Actually I believe its just amazing that the old H bodys weighed only 3300 in the first place.

What is this about an AWS Bonneville ? Lately have noticed my wife'* car tends to act oddly on moderate right handers at 40-50 mph, feels like the rear end is moving out. Quick look did not show anything obvious.
