Paging Naja !

Oh, it's been running for 8 months (minus considerable time in the shop(s)), but it got torn down after the first 30 miles (see my water pump threads).

We're getting there. My EFI guru is no longer available - job change; not making himself available to do the fine tuning on the programming. But it is running decently. The guys at Texas World Speedway and Mid-America Challenge (Hearland - Topeka) thought it sounded pretty good on the straightaway at 120.

Don't have to estimate hp or torque. It dyno'd at 491 hp at 5200 rpm, and 548 fp at 4700. We were kind of disappointed until we considered that the Torker II intake is a significant restriction. We previously did some work on the new Edelbrock heads to bring them up to 'spec' for a 533 ci engine (with the .662 i/e roller cam), but didn't do too much with the manifold. We figured it wouldn't make a lot of difference because it is not a high rise and there is only 'so much' that you can work with. We built the engine for torque, reliability and highway cruising, anyway. The Torker II is good for that.

I wanted the injected 58mm Webers (from TWM), but they were not in production when I had to get something. With that setup on the engine, we would get the 700 fp that we were hoping for (and let the hp come as it may - say 650 (?)). True to an injected stroker, the torque curve rises very sharply. They only began the data logging at 2600 rpm, but by that point, the engine was already doing 525 fp.

I didn't want to mess with the scoop (I like the proportions of it just like it is), so the Torker II was the only combo that I could fit under the hood (the TWM induction would have fit, also).

We've done a little fine tuning with the program. After I get my wife to feel comfortable driving the car (she hasn't driven it, yet), I will see about doing the rest of the fine tuning myself, now that I got someone to let me know what to do. There is another experienced fellow in the area that I want to get with to have him explain some of the finer points of messing with the parameters.

I've just been 'wrastling' with the overheating problems, so that I can drive it under most any situation for as long as I want. I think that I am about there, but I want to try a couple of things (like getting the 'correct' water pump speed) to give myself a little cushion.
