This thread was posted due to the high volume of PM's that I have received for overlays, final numbers, and idle quality etc etc. Well to simplify the task they are conveniently located in one location. Thanks to everyone that has PM'd me about my car, and also to eveyone that has posted up in support of my project. Its been a long time, but the results completely justify the wait. Lg Motorsports for all your performance needs.

So as you can see here the 346 with basically the same parts as the 402 doesn't even compare. That is unless you wanted to spin these motors to 7500 rpms. Had I planned on spinning the 402 to 7500 rpms, I'd have opted for a better flowing head because it was a foregone conclusion that as the RPMS came up the 402 would move a lot more air then the 346 and would need to breathe better up top then what the milled afr 205's would allow. You have to admit though, the 346 was coming on strong and had we pushed to higher rpms I believe the 346 would've made more hp/tq at 7500, perhaps as early as 7000 rpms. Only due to the heads inability to flow enough air in the 7000-7500 rpm range on a 402. Doesn't matter though, the afr 205's did their job on the 402 better then expected, and I couldn't be happier with the results.

Just can't wait to drive it.

 

Just to make things easier how about no more threads about your car? We're at 11 threads now - everywhere I go it's there...I can't escape it! I'm just kidding with you, it's just making all of us N/A stock displacement guys jealous!

 

I hear ya bro, sorry to do this to ya but I am about to do 11 more !!! LOL. Just kidding. Thanks for the support.

BTW 3/24 looks like the day I'll be flying down to drive her home. So you'll have to endure another thread about my first impressions, etc, etc, etc. LOL

Stay cool brother
