Does anybody have a 70mm accufab or similar throttle body they want to part with before i order a new one? Thanks!

I’m looking for a TA performance VBand clamp. They are an oddball width and so far nothing ive bought works. If you have a good used one I’d like to buy it. It’s all I have left to fire up my new engine. I’m about to bolt the stockers back on if I can’t find one. Thanks!

Looking for a Mild Steal or Stainless TA passenger side header. Thanks!

So a while back I posted this thread about finding my bottleneck. The car had been 10.61@127 in that post and I just wanted to update. The car can and does 60 in the mid to high 1.4s but driver issues and rushing at the line preventing me from getting there on this trip. So im still looking...

As the title states, let me know what you have! Thanks!

Just wanted to see who was going and if you are try and recruit as many other Buicks and LS as you can! October 20th! Probably lots of turbo and supercharged Coyotes are gonna be there laying down some fast times so the more 10 second or faster cars we can get to get an early lead the better!

I went to the track for the first time in about 5 years this past Saturday. Weather was good for this time of year at about 900-1000 ft DA. My previous best had been an 10.70@127.8 on a basic combo. Girdled 8.8:1 234 ci, ported stock heads with bigger valves, 210/215 FT roller, PTC 17 blade...

I have a ATR 3” downpipe. It was modified for the RJC big 1.625” puck. The downside is that at one point I beat this thing up pretty good to clear my old ATR headers and the control arm. I was younger and didn’t think about motor mounts being the main issue. None of the dings are visible from...

Those that have messed with the KC valvebody, what would be the results of using the BRF TV valve and spring setup in the KC? Somebody has previously messed with my KC valvebody including different springs and a spacer etc... just seeing if anybody has tried this and what the results were.

I recently replaced my old KC valve body due to a few weird things it would do with a unmolested BRF. I swapped over my stage-rite brake stuff and the accumulator/line bias spring from the CK Kit. Everything was perfect for 3-4 weeks afterwards. Then it stopped downshifting at WOT and just...

I may have an opportunity to upgrade turbos and was going to see if anybody was interested in my PTE6776. It's a 3"/2" turbo that comes with a .85 and .63 PTE exhaust housing. It has maybe 5-6000 miles and 0 shaft play. It has been used with a turbo saver since day one. It's still on the car...

As stated I'm just looking for real world setups and how they have run with one of these turbos? Im considering a Turbonetics HPC Billet / F1 72/68 or 69/68? I know the Precision turbos are more popular and I may end up with a proven 6766 but just considering one of these as I've always had...

200-4r gurus. I finally have my new stroker build up and running after a couple years of down time (new baby and not enough time). I have built quite a few 200-4rs but do not consider myself a guru with the hydraulics and this issue is plaguing me. I run a KC valve body on mine with a stock...

Alright a little background. I'm working on a friends 87 GN. It recently started blowing the fuel pump fuse. Since Ive known this car, the pump has turned on with the key and stays on (no priming somebody bypassed it). I found somebody elses rig job from way back when. A wire was spliced...

I'm selling a set of adjustable hardened pushrods. I don't know the exact specs but they are adjusted to about 8" now and were used with morel roller lifters and stock rockers. They have never loosened and have been 10.70s without issue. They worked great but I finally got roller rockers and can...

I have a friend looking at a GNX for sale. I have been trying to search but haven't found an answer. The car has a moon roof. Is this for sure an aftermarket? I've read all but one were hard tops. How much does this hurt the value of an original very low mile GNx?

I have a few parts that I'm selling. The first is a GM timing cover that appears unused setup with a HV gear set. It was bolted to a fresh short block but never ran. The part number is 25522650. Asking $200 shipped. Next up is a Mease upper plenum. It's a polished sheet metal plenum. It...

I'm selling a pair of 8445 heads that came on a short block that I bought. I am using my heads on the build so I'm selling these. They are fresh 0 mile heads that have been milled smooth very smooth. They have 1.77/1.55 valves with new beehive springs setup at 1.75 ( I think they are comp...

Any input on the old Mease sheet metal upper plenum? I got one of these in a package deal last month and am debating running it or not? It looks nice and the welds are great but would it really be any improvement over my ported stock unit with the RJC plate? My new setup is a 252 ci stroked...

I am in the process of diagnosing my engines issues. After doing a leakdown and finding a hurt number 1 cylinder and a few iffy cylinders I am pulling the motor. But in the process of the leak down I found two damaged valve stems. What would cause this? I run Kmotion K750s at 1.75 installed...
