Wondering if the 373 rear gears are better for performnce and speed in a street & strip foxbody or would the 308 or 327 gears be better
Don't fear the gear. Especially with an aod. I'm still a fan of 4.10s with that trans. 6500 at the stripe would be around 120mph which is where a hci vortech car should be (assuming it has an hci, at that power I would think it would and should have no problem going closer to 7000).
Exactly what I was trying to get at with his peak power rpm. No point in putting a gear in it that spins him to 7k on the big end of he is all done by 5500. And vice versa, he needs a gear that will get him into the power band.depends on the cam.... Why spin it out to 7k if your done by 5800??
I had a custom cam made for my current build blower cam 114 lsa idles great makes power everywhere but noses over at 6k so i shift at 5800. stock limiter. 3.08 gear t5
Stock lifters here to 6500 routinely, father n law takes them to around 6800.Stock lifters with proper springs can be good to 7k, not a problem. And any supercharged car would (should) be tuned anyway and the limiter raised.
