Holley 390 angle
Posted: Tue Jan 15, 2008 8:07 am
Hi
I have just bought a Holley 390 for my RV8 in a Gardner Douglas Cobra with an Edelbrock Performer manifold. Because the Engine is installed level the manifold angle tilts forward. I bought an angle plate (5degrees) when I got the carb, but if I put that between the manifold and carb then it tilts back to far!! How critical is this angle and would I be better just leaving the wedge plate off and accepting the slight forward angle (possibly 2.5 degrees), or should I get the wedge plate machined?
Thanks
Martin
