I have built up a replacement engine for my 72, so as to save the original one. It is a 355 with a steel crank, good rods, a comp cams xe274h, vortec heads, an edelbrock rpm performer intake with a holley 750, and headers with 2 1/2 inch exhaust. The car has a 3.36 posi rear in it with a th400. My question is what torque converter to use. This is my first auto, and I have never had to use one before. Any advice would be helpful. Thanks, Tom

B&M or TCI, make very good torque converters. With 3.36 gears and a cam duration of 274 degrees, it is recommended to run about 2400-2600 rpm stall speed.

Thanks Sarge. I'm looking at a B&M 2400 that should work for it . I appreciate the info.

Hi myself id use a 2500 sometimes smaller is better!While i'm chatn to you how did your hood fit with the RPM ive just fitted one in my 70 L48 it looks scary high love to know how you got on !! Cheers Mick (down under!) Austraila

Micko, I don't know as I haven't put the hood on it yet. I have an aftermarket L-88 hood that the guy I bought the car from gave me, so if the original hood doesn't work, I will use that. I saw your post, and was watching to see what kind of answers you got. I hope I can find an air-cleaner that will let me use the original hood.
Let me know if you find a solution. Thanks.
