I don't have all the nitty-gritty details that I'm sure some of you would like but I did give a lot of trust to the shop. I told them what I was after, they asked me some questions on things like how to I plan to run the car, is it set up for race or street, transmission, rear etc.. I told them I wanted a really strong street motor that's not going to be grumpy and needed to be tuned for the street then race gas and tuned again for the track. I wanted to drive to the coast for a summer trip and not have to worry when I got to sea level.

I tell ya, I still get a grin when I recall them hitting the start button on a cold start. Instant on...no cranky cranking. I wasn't really not sold on the idea of EFI. I was actually leaning towards a dominator but then I remembered the days at the track, spilling fuel on the intake, dropping jets in the pits, try this-n-that with timing, but I'm a convert now. Maybe not the ideal for drawing out max WOT power but that's not the mission here. I had to keep reminding myself of that.

There's a question about the head bolts, honestly, I don't know why they chose them over studs. As the builder indicated to me this motor is just loafing along. The cam starts to poop out about 6000 rpm. He did a couple pulls to 6K which sounded like music. I presume because of where I'm planning to turn the RPMs and compression, it may not need it...I don't know. If you think this is a concern I could ask though.

I'm headed back down into town next week to pick it up. I should have a bit more info. The guys at MadCap Racing (I hope it's ok to post the name of the business) in Denver are a great bunch. As I was leaving the shop I saw a couple old Pontiacs in there in line waiting their turn for a refresh.

Once again to everyone here. I had been lurking then started asking questions and having learned from previous mistakes, don't build a Pontiac like a Chevy. Take advantage of that long lever for street driving. 4L80e is next and out on the highway for some cool smooth cruising.
