stupid ?

I've always wanted to do a 61 bubbletop with a 348. Big 4GC, big valves, enough cam, decentheads and oversquare bore & stroke at 250 hp should work. Has anybody got one that I can borrow?

If I still had some W motor stuff, I'd be keeping it to myself. I was a fool for letting it get away. It's too damned expensive and too damned hard to find now. I'd probably be too scared to race it, unless I'd gathered up more stuff.

In the mid 60's. My brothers 63 Super Sport 327/300 with a 4 speed and 4:88 gear, 7" recap slicks, no headers but a nicely done set of fenderwell cutouts driven to the track (PID) ran 14.22's. No competition for the Jenkins preped Vette running the same class. A friend's 62 or 63 Catilina factory 389 tri-power 4 speed car also ran 14.20's.

Car is allmost done. One peice drive shaft, 4 link Ford 9". G Force trans.

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.
