4.30 gears with T-5

Rick 91GT · 09-10-2001, 10:23 AM

Are you interested in getting rid of the 4:30's? Drop me a e-mail with a price and the any other info rhawver@strouse.com. I was getting ready to order a set but if you have them for a good deal..

Did you pick up anything by doing the swap? That GT-40 intake will limit you on the top end, the heads will flow great numbers but the GT-40 will fall off above 5800 same with the B cam.

I need to go to the 4:30's due to my cam profile (needs 4:30-4:56 gear) and wanted rpm range at the traps. I am only going through at 5200rpm with the 3:73's, the 4:30's should put me through around 6300-6400 which is where I am currently making peak power. Jeff has a lot of good points, it really depends on your combo a lot. I can't wait to get the 4:30's in and grab some mid 11's. I would think the 4:30's are too low for use with N20 anyway.
