The LS7 would be fine in a C3. You're a lot lighter than a lot of other cars that put down that kind of power in a V like mine. As far as the rear end, don't know about that. I don't know what kind of numbers a LS2 will throw out during smog inspection. Depends on the cam. But honestly, with heads like yours at 11:1, you can get away with a little more.

The point you bring up about the rest of the drivetrain is a concern though. Too much power and you'll break the diff or axle. So maybe a stroker isn't ideal.

Street tires probably don't matter so much, but sticky tires and that much torque from anything like a launch on a Dana 44 (type as in a C3) is probably asking for it. Many Corvette oldsters are surprised mine has held up as well as it has with the engine I had given all the launches at the strip. A 12 bolt solves that problem, but poof, a whole new set of expenses and added weight.

Yea, at this point, a OEM rebuild is probably more than enough. A nice cam will be more than enough to get into the 400s at the wheels. Just let me know if the block isn't salvageable. I'll hang onto the LS2 for a week or so

More displacement and good compression will make the engine more efficient and that means passing the sniffer easier. If you look at the TSP you can order it with whatever reluctor wheel you want, I have only read one or two bad cases from TSP. If you are that concerned, have them send it to you unassembled and have it done here.

I should know by Friday. I'll keep you posted.

Just wanted to let you know, in the event I can't use my motor, I'll stick to GenIII, so don't hold the LS2 for me. The harness mods are more than I want to get into and I have a line on a couple LS1 cores if need be. I might contact you about the 241 heads though if you still have them.

243 heads is what you're after. And no, I sold it. Sorry, if I come across some I'll let you know. The 243s are slightly better performing due to better valves and smaller combustion chamber. They are the same as 799 truck heads, and the truck heads can usually be found very cheaply. If you do end up going 243s change the valve springs. There was a known issue with early 243 valve spring breaking. Better to be safe than sorry. You can get LS9 springs from lingenfelter racing for $70.

Naturally this is taking longer than hoped. I basically dropped off my block and heads while they were getting out race engines for a tv show of some sort and have been following up with that. Ah well, fortunately I'm not in a rush, but I would like to see some progress. Apparently there is a brand new zero mile crate LS1 close to me for $2,600. Tempting sense it'd be dead reliable, but I don't think I can take the near 100HP drop.

You know the rules, take your time/budget/sanity and multiply by three.
