In the link above the comp was 8.25 and the reason for that is to protect myself and the customer, he was pulling 20,000 plus pounds. I wouldn't want a 1.900 seat put in a production BBC head I was towing with because I wouldn't want to get that thin in that area, thats why I use a 1.720 valve. If you would read the link, you will see power was 550 HP with 600 TQ. No need to apologize about the car, its no problem for me.

HP thank you for the info. I did read the article in the link. But, I did see where there was possiably more info to the story (picts and all) that I did not have access to until I register. I have just not done that yet. But, thank you for the info. Again your car looks and runs really good. Have a good one.

Update: I ran the car at Bandimere in some 8800 DA conditions, 24.24 baro. I was able to figure out the off idle stumble and was able to run a 1.47 60, 6.95 660, 11.05 1320 on Sunday, If I could have figured out the carb Saturday when the baro was a whole 24.38 and had my 29.5s on there surely I would have seen some 10s.

HP how would it have compared if you ran the next bigger cam 238/248 114?

I had 9.3 compression, I think it would be slower, but I don't know.

660 6.82
660 98.8
1320 10.86
1320 120.4

I'm really impressed your horsepower and weight make that seem like a 11.20 combo not a high to mid 10 second combo. someone knows how to build a efficient car that works. nice job
