I’m planning (as I’ve repeated to people at least 100 times on this forum in the last few months… I swear it’ll happen and I’ll stop talking about it soon!) on swapping new heads/cam/intake on to my 351, expecting it to push 425 hp/tq (351w, 9.5:1, Trick Flow TW heads, Stealth, compcams 274xe… the same combo but with a roller 331 made 438 hp in a magazine article.. its on AFR’s site..).
I have a t5 in my car now out of an 89 GT. It works great now. However, I have my doubts as to how it’ll handle the engine. That’s basically the question… while my engine is out at the shop is the easiest time to swap in a new transmission (and pull the current one while its worth something, whereas if I break it…). Should I do this? Tony at Astro transmissions says his super-alloy t5 (essentially a T-5z) will be fine for the aforementioned application, and that real high-end T-5s (gforce, A-5, etc) are overkill.
There are a number of factors that might help my current T-5 live a lot longer than it would in most cars. My 66 is really light. I have relatively tame rear gears (3.25). I do not plan on running drag radials or slicks (though I may put cal-tracs on it to reduce wheelhop… I hate wheelhop with a passion). I don’t race the car (the nearest track is 2 hours away, and is LACR… which sucks). I don’t powershift the thing or drop the clutch at 3k rpms. Its abuse will be limited to things like spirited country road driving, having fun on highway onramps, etc.
So yeah… what would stangnet do? A new T-5z is about 1500 shipped from summit (if anyone knows anyplace cheaper please let me know), and I figure I could still get 500 for my T-5, so a total outlay of roughly $1,000.
