I have a 350 that the guy before me threw in, he has done some serious mods to the engine, and it seems to run hard. He has also put 3.73 gears in the rear and it has a manual transmission. Just wanted to know if anyone had a basline for the 350?

Thanks

 

If you mean an L98, then it varies by year. 90-92 was 245, before that it could be 220-240 depending on year and options.

 

Is it TPI or carb? If it has serious mods like cam, heads and intake it could have 240-450. Find out exactly what the guy did and the guys on here can get ya real close based on their mods. Good luck.

 

Since its not a stock TPI 350, just get it dyno'd and stop guessing about it. You said it was not not.

 

Hopped up 350 manual, with 3.73 gears...must be fun to drive =D
