Well, first off i'd like to say hi!:welcome: Now, I got a 1970 LeMans with the original 2bbl 350 that was equiped with dual exhaust outfitted with flowmaster mufflers. Other than that I think the engine is stock. The guy i bought it off of said he overhauled the engine like 2-3 years ago. Stated he made the 350 into a 396. I asked around other boards to see if this was possible. People said yes, but was hard to accomplish this without some strange bore and stroke set up. SO i dont know whether it's a true 350 or a 396 So having said that, I would really appreciate some help on bumping up the hp since Im not familiar with Pontiac engines and I'm still learning. I want to keep the 350 engine seeing as i heard from my car club that the value of the car will drop if i replace the original engine. What carb, headers, intake, cam (If you can help since i still dont know if its a 350 or 396). What kind of rwhp will i be looking at when I these upgrades?Also keep in mind that will be a daily driver, but with balls! One last thing, is there a way to find the size of the engine without having to pull out the engine and opening her up? Thanks much!!!
