My engine is a 351W supplied by Olthoff racing. Supplied with a 750HP Holley. I had the car on the dyno when I got it from the first owner and it was too lean. I upped the jet sizes about 3 step to 70 for primary and 76 for the vacuum secondaries. Runs good. It probably is just a little too large a carb, but I cannot complain. I get about 24 MPG on the highway.
