Cleaned up the other head today and then installed it. I also got the pushrods and rocks on and adjusted as well as the front accessories and blower. Tomorrow I'll get spark plugs installed (should have done that before bolting the heads on), then the lower intake and valve covers and then drop the distributor in and run the wires. That's if I can finish it all before dark. Then I'll finish everything else up on Saturday and hopefully have it running.

The only two pictures from today.

How it sits now.

Those HGs look for serious.

These are what I was running on the 302 before, I just didn't want to spend $90 each on them when I built this engine. I was hoping the Mr Gasket MLS gaskets at $35 each would work. But decided to spend it now.

She running again! It's so much nicer driving the car without the smell of burning oil. Now I just need to charge the A/C and then have the tune finished. I'm going to see if Steve has an appointment for this week.

I have my appointment with Steve scheduled for next Tuesday the 9th at 9am!

Dyno tuning is done but the car isn't. It's good and bad when Steve tells you that you are making too much power! :rolling: To be more specific, he said that I'm making too much for not having an intercooler. He told me that I need to install methanol injection because the inlet temps are way too high for the power the engine is making and he's worried that it will pop a head gasket if I beat on it which we all know I'm going to.

So, what's it making? Let me start by saying that we again had trouble with it spinning the tires in 4th. When the car was cool it put down 476 rwhp and 470 rwtq but that was with the tires spinning. That was on the pump gas tune. In an attempt to keep the tires from spinninig Steve would go full throttle in 3rd to heat the tires up but then the IATs would rise so on the pull the horsepower would drop. After that Steve made the pulls in 5th but again the IATs were so hot that the car was making less power even though it made more torque. On the final pump gas pull it put down 467 rwhp and 490 rwtq. This was with a total of 15 degrees of timing. It was actually the last pass that he made for the session which was after he finished the race fuel tune.

For the race fuel tune I added 5 gallons of race fuel. Total timing ended up at 20 degrees on the race fuel tune but again because of the IAT the race fuel tune didn't pick up that much over the pump gas tune. The final pull on the race fuel was 494 rwhp and 504 rwtq.

Here's a printout of the last two pulls which are the fianl race fuel pull followed by the pump gas pull.
