Hes referring to the 'strength' of the motor based on dyno numbers. Hes inferring that you had a stronger starting point. Like my Z with full exhaust, CAI, underdrives made 295rwhp@5500 and 320rwt@4200 (with a miss), strong for what mods that I have (or so I have been told). Hes just saying that based on his (grygst76) mods and dyno numbers that his LT1 isn't as strong as yours or mine, assuming that you dynod strong closer to stock, as your h/c numbers are awesome.

Oh, I see. A "." between JGeorger and his would have made it clear.
My84Z - are you assuming my car started out strong or have I told you (or did you look at my website)? Sorry but I have trouble putting names to faces....
Anyway, my car mostly stock dynoed 265 rwhp/306 rwtq. This is a factory Ram-Air rated at 305 hp. At the time I had underdrive pulleys, airfoil, K+N, and full synthetics. So that was about 312 at the engine with the M6.... Just about right. These dyno numbers were attained on a different dynojet (P+J's speedshop in Buffalo, NY) than the post heads/cam numbers (which were obtained at NEDT).

Yeah, I see what you're saying. It seems he would have had rockers, headers, cat-back and TB bypass over me. Maf is tricky cause it can screw up your AFR - but it usually serves to lean out the stock overly-rich AFR. grygst76, how was the AFR on your runs?
I know a lot of people gained power switching from shorties to long-tubes.... Also how many miles on the engine? Is it in good condition?

In all seriousness, those heads will hit some massive low end TQ, but I don't think they can possibly hit 400. I was shooting for 350 and some people said that would be a stretch........
Anywho, that muffler still FS?

the car has 108,000 miles on it. the opti seized a little while after the dyno run. the a/f was 10.9-11.0 and I did not have the full CAI, my elbow was ripped and letting air in. I went and dyno'd just to see where I was at so more then likely now I am pushing around 280 since I fixed all the problems and replaced my loose as hell timing chain..I'm shocked the thing was still on it was stretched so bad. I know everyone here talks of me not being mad if I do not hit 400 but if you read more I will be doing other things to it as well the cam I'm putting in is your average off the shelf, but it's getting a facelift at my dads machine shop
the heads flow pretty good, but they are also in the shop as we speak getting another massage. I have a stock manifold that is getting port matched to the heads as well. Lot of things to be done and I can do the install myself, BUT I do not have the time it will take for one person to do it. 2 people make it faster.

It's a dynomax bullet muffler and its welded to prefit the full loudmouth system when you get rid of the resonator. If you do a search there is some people who made their own loudmouth system and it cost them around 150.00 for everything except you already would have the muffler so it might run you 100.00.
