I bought a 98 4V motor that I sold the 4V heads and few other items and just kept the shortblock. So I now have a lighter Teskid aluminum block for my future build. With lighter aluminum block with 2cc dish pistons my CR will be 11.75-12:1. The heads were Stage I ported and 1mm larger Crower...

Who is running high compression NA motors? Mine is 12:1 with VT Stage II cams. The heads are mildly ported with oversize valves. Just wondering what to expect rwhp with high cr motors. Thanks

I have a 98 4V that I bought to do the 2V to 4V swap. But after reading I'm a little concern about a couple of things and wonder what your opinion would be on this issue. Remember this is a 98% drag car and I'm staying NA. On the 2V: Forged rotating assembly, 9:1 CR, & 262AH cams made 272rwhp...

Will E7 91-93 GT heads fit on a 1967 289 block without issues? Kurt

Even though I had a crappy time running my dail in this weekend I still ran my best time on the new setup at [email protected] This setup is still new to me, only have 10 passes on setup including 6 passes at FFW. I had a good time though at FFW, camp out and raced. You can't ask for a...

here the pics from a car show I went to two weeks ago with my Cowl Hood Kurt

I had my 4.30 gears installed and they whining like a $#*&%, they are FRPP/Motive gear and the installer has done my last 6 gear changes on all my cars with any whining at all. He thinks since they are motive gears box in FRPP that motive cut on the teeth might have a whine to them. The pattern...

I just bough the Summit Racing plastic racing seat and was wondering how you guys mount in your cars without rollbars and still using the factory seat belt? I really need help on this. Kurt

Is this really worth anything at the track? I see people doing it and I'm wondering what they saw with or without the pass headlight? Thanks Kurt

well I went to D42 today. I had the 2nd to 3rd shift fixed and now it hits 6K and shift instead of 5500rpm, but now I notice my 1st to 2nd shift is short 5600rpm, which blogged it down a little. There was a good head wind today which really mess with our times. I made it to the third round where...

Really was not sure how they would of looked on my car, but I actually like the look, still not sure on the wingless look yet :)

where can I get the tools needed to do a cam swap while the heads are on the motor and in the car? Now of any short cuts or tips to help make the job easier? Kurt

Does anyone have dyno numbers on the Comp Cam XE262AH and the VT Stage 1 cams? I'm not really interested in peak HP but HP increases over the entire powerband. I'm having a hard time picking between the two cams. My car will be raced this summer in bracket races but it also is a daily driver...

can this be done? I have a 93 GT and I can get free new springs that was on a 04 GT. Will these fit my 93? Kurt
