stupid ?

Doesn't sound stupid to me. All of the hi po 409's ran a 4 speed. The 348 might work pretty well with an automatic,with the available torque, a powerglide might be the hot set up. Could you imagine what a nasty legal 348 would do to a metric 200?If that set up gets approved as a turboglide replacement, it might just work pretty well.Also,check if the 340 horse 409 heads and intake are legally allowable updated replacement parts for the earlier 348 stuff. Also, I knew of someone who tried a 348 and the factory aluminum intake for the hi po motor was allowed. Now,good luck finding it.

I am going to start out with a big block to sort out me and the car.

Once I get that done then I am going to try either 360 HP (single 4 Bl) or

409 HP (dual 4 Bl) depending on the HP they make. If that don't work out I can

go to small blocks or GT and run lots of combinations.

First thing I have to do is make the car work, which is next.

Jim, I would definitely be looking at a 348 for SS more so that Stock.

Seems to me that Herman Chapman did this years ago.I remember a Super Stock and Drag Illustrated issue in about 1976 where he did that with a 348 250 horse combo.It was pretty wild for its time. Now, who has a stack of old Super Stock magazines?

I see a lot of these X frame cars in the old magazines. What did they use for rear suspension? Did anyone make a bolt on traction device?

This is from memory, haven't had one of those cars in years, but I think this is correct: They had a three link, one upper and two lowers. Think of the later model cars, A and B body, with one upper control arm left off. Back in the day, a lot of people went to a salvage yard, and cut the control arm bracket off the frame and rearend housing of a wreck, and put the second upper control arm on. Don't think NHRA would really like that. Off hand, I do not know what the aftermarket offers for it.

I flowed some 256 casting number heads years ago researching a '61 305 hp 348 and the numbers showed them to be competitive against a 461 small block head. The question was always what the 75 degree block surface would do to the flow.
