You say you can show it. Post a link where it is discussed in a forum or other web site BY THE OWNER OF THE CAR.
I know its possible and I know what it takes to achieve that level of performance.

Yup the twin Buick GM turbos work very well. (TWIN being the key word.)
sorry i never even saw this reply
heads have 1.72 intake valves
The block and heads came out of a 80 chev pickup(not original motor) and near as we can tell, it has 150k on it. Has dogcrap 991 small valve truck heads with 76cc chambers and 1.72 intake and 1.5 exh. valves. Should be 8.6 to 1 with 4 valve relief flat tops that are .022 in the hole and a .038 gasket.
no water to air cooler here here is the thread

and if u dont want to take 3 years to read all couple hundred pages or so

For those of you who dont want to go blind reading all this, the old used up motor was pulled out intact and running perfectly after going 9.37@150! Best power number was 738 whp @ 25 psi and a 75 shot of NOS. Ring gap ended being .090 on the top ring when i finally pulled a piston out of the hole. Yikes! :doh:
