Inexpensive Gremmie Street/Strip Build - Thoughts? - The AMC Forum

Fellas -

Have been thinking about an inexpensive Gremlin street/strip build; figure I could find one fairly cheap and I have enough spare motor/drivetrain stuff in the garage to do most of the build.

Here are my thoughts - .030 401, stock crank, stock rods with ARP bolts, forged flat tops from Bulltear, 291C heads with some garage porting/good springs/stainless valves, healthy solid flat tappet cam, steel roller tip rockers, Torker, 850 dp, MSD 6AL, full-length headers. Would want something that would run on pump gas (maybe with timing dialed back) or maybe a pump gas/race gas mix. I've got just about everything in the garage except for the valvetrain. Any ideas on how much hp I could make with this combo?

I have a spare T10 (close ratio), but I think I would run a 727 (manual valve body, shift kit). Will this be tough to fit? Crossmember and firewall/trans tunnel? Figure the V8 Gremmies came with a 904 trans, but not sure on size difference between the two. Think I'd go with a 10" converter. Would I need to cut a driveshaft to fit or is there a stock driveshaft in the right length? What about a trans crossmember - what would work here?

Out back I would go with an AMC 20. Anyone have the overall width and the spring perch to spring perch width? I do have a spare 68-69 AMX rear diff in the garage; if it's the right width, I could weld the tubes to the housing, reinforce the spring perches, get a set of 4.10 gears and some Moser axles, and use the spare Detroit Locker that I have.

If I found an original 6 cylinder car to start with, I'd need the correct engine crossmember, right? I guess I'd also have to replace the rear; figure the 6 cylinder cars would come with the AMC 15. Guess I would need a V8 radiator, too.

Any thoughts on how much the car would weigh? Figure manual steering, brakes (I've got a Kelsey Hayes front disk setup I could use), and no A/C. Would probably leave the full interior in place, but add a roll bar.

I'd likely run drag radials out back; any thoughts on how much tire I can stuff under one of these?

Anything else I'm missing?

Any thoughts on what kind of times I could expect? Somewhere in the 11's, right?

Thanks,

Scott

	You don't necessarily need a v8 crossmember, Bulltear makes bolt on mounts to convert 6cyl cars to a v8.
