Im thinking that I have all the right stuff....anyone?? I bought most of these parts so long ago, I havent even checked the numbers...they werent making so many fake/repo parts back in the day!! Im really not sure on the t.i.ignition stuff..

BTW, we did not use the NOS cam and lifters as more than one person told me to use a newer cam as they are much better, although I got a cam with the exact ZL-1 specs.

I wonder what power these motors could make with a good match porting and a roller cam???

this is the last pic before the dyno!!!

Before John Armstrong sold his Super Stock 1969 Camaro, he was running it in SS/BA with the ZL1 engine. For anyone who follows NHRA racing, Armstrong was the first Chevrolet Super Stock car to run in the eights. 8.88 at 149mph to be exact. NHRA would not let him run in SS/AA at that time. Armstrong is probably the best and smartest BB engine builder in the country. Well, actually he lives in Canada.

Cool. I know when we dyno'd mine, it was 465 with exhaust manifolds and 535 with headers!

apparently the headers were the limiting factor!!! 70 HP difference....I did not bother dynoing my motor with the factory exhaust, although it will have to be installed that way.....or????
