A few months ago I posted results with my 243's & Hot cam. I came out to 370/363 to the wheels. It was good for a while but I felt like I wouldn't be able to keep up with a cammed & stalled Fbody in my GTO. So I gave AI a call & since I already had a set of 241's laying around I sent those in for the 219CC port job. Along with that i had them spec me a cam. With those mods I still have my UDP, long tube headers 1 3/4 pacesetters with cutouts & my LS6 intake mouth has been open up to 85mm. With the cutouts open it put down 430/380 to the wheels. This is with a stock air box with a drop in K&N filter. I'm darn satisfied not only with the numbers but the car pulls like crazy all the way up to 6500. I put this to the test against a 99SS that has a stall, cam, full exhaust & an air lid. The race was over when it started. I pulled by him so hard not getting traction till third gear. This was really amazing because I had continental street tires & he had Mickey thompsons & im sure they were drag radials. Granny shifting I beat him by 5-7 cars in the 1/8. Anyways with a Fast 102 & a ram air type intake on this car I'm sure it'll be closer to 460/390 to the wheels.

60 rwhp is a awesome gain. Now get it to the track

thesoldier

I plan to once the track opens back up. That's where my feelings would really get hurt lol. At best im striving for 7.0's-7.5's but I believe having the stock gear may hold me back somewhat on my 60ft.

Did you chose the high compression 241 heads? Nice results,probably 15 left with a fast.
What cam did you go with?

I'd say more like 20 to 25 with a FAST 102.

Mine is a ported fast 90. I gained 13. Hope he does gain 25 but every combination is different

Why are the AI 241s putting that much more than AI ports 243? Or is the extra umphhhhh from the higher compression the 241s give?

I just depends on the combo and on the dyno. I've seen really impressive numbers with AI 243's too.

I didn't choose the high compression 241's. The heads were milled .020 though & the cam is an AI cam. I can't tell you who did the grind. The specs 230/238 .605lift on a113+2. To be honest even though it was a dyno jet that thing isn't forgiving at all. On my old setup with the hot cam & 243's the average person seems to make 390-400 with an m6. I expected 410-415 out of the AI heads & cam package but they definitely made a believer out of me.

Dyno numbers are a tool. You gained a lot of power and a lot more fun. I may send ai some 241s and opt for the high compression model and a bigger valve . I have a 4" bore.
My 241s are barely ported but make good power with a 2.02 . I have another set i can send him to do.

You really can't beat the AI 241 CNC program. I'd choose to go with the high compression CNC 241 program if I were you.

This is very true. I gained 15 rwhp with a FAST 90/90 on my heads/cam LS1. We swapped the same intake onto my brother's heads/cam LS1 and he gained zero.
