    Has anyone ever installed a TA aluminum block in a tta? I really want one for one of my cars eventually. TA blocks are obviously designed to use stock 8 bolt or 14 bolt heads. Is there any way around the issue of lifting a tta head with the TA block?

    Since the stocks heads are the problem to start with i would think it would be a issue with either block if you are trying for 10.5 or faster... that said i have never heard of someone putting stock heads on a TA block, but i'm sure it has been tried.

    Damn! There has to be some way around the head lifting issue. You guys are obviously running cometic head gaskets correct? I wonder how much it would cost to have TA Performance make a batch of our tta heads in aluminum with 14 bolt provisions? I know im dreaming

    I personally wouldn't run Cometic gaskets, i would rather replace a head gasket vs grenading a eng.

    Come up with the 100k and I am sure Mike might think about it.

    Well, I still want to retain my heater and AC so I don't see how there's a way around it. How far have cometic head gaskets taken a tta?

    Problem with the GN engine was not heater and AC space, big issue was the down pipe / exhaust causing the real problem and they notched the frame rail for clearance on the passenger side on the first prototypes but for production it would have cost way too much in tooling etc. So the more narrow FWD heads solved that problem.

    I think a few have been around 10.2 in the 1/4 with modded tta heads, no idea what gaskets they were using... but i bet they bought them in bulk lol...

    Why do the tta heads lift at a certain power level? The GN iron head has been low 9s high 8s with cometics. I'm trying to learn all I can about these cars. Thanks for any info in advance.

    I had a TTA block and TTA heads down to 10.5 ET in the quarter mile. It was not going to get past that for me with the tta heads.

    I now have a TA-Performance Block in my TTA, as far as I know I am the only one. It needs custom motor mounts as the TA motor mounts from HR Parts n Stuff don't work. Motor has been great and it is nice to not lift heads, also I am pushing far less boost than before and obtaining better results. My car has ran high nines at a mile above sea level. I hope to take it farther and maybe even travel to mission raceway in British Columbia to obtain a better ET since that track is at sea level. The race season here is so short and family and work keep me busy.

    Jarredsoon,
    Great performance with your new combo. [email protected] at the elevation you did it at is awesome. I'm also putting a TA block in a TTA. You wouldn't have pic's of your build as you were putting together would you? Just curious if you swapped K-members, ta or Champion cylinder heads, size of the down pipe etc. Any suggestions would be greatly appreciated.

    Would there be any more sealing/clamping advantage by going with a TA block and using the tta heads? Has anyone ever O ringed their tta heads?

    Not sure about that but here is the problem... air in air out, tta heads can only move so much until you hit the " wall ", so lets say you stop the heads from lifting, guess what happens next.

    93/Alky, 24# boost, 6466 turbo, with new trans and TC i am feeling pretty confident about low 10's, btw it has ported polished big valve tta heads, i may have to go with bigger inj's with this turbo though.

    My gosh! I didn't know you were running that large of a turbo. That sucker is gonna fly. I put a 6766 on my t type and so far it spools really fast but I haven't gone wot yet. It's only got 150 miles on the motor. Truth be told I'm scared to go wot!

    At least with the bigger turbo the BB allows you to run the 82. exh. housing... move it in move it out... no wait that's what she said lol
