It’s been awhile since I last posted my progress…

I have finally gotten my linkage sorted out. It works great from what I can tell with the manifold off of the engine. I had to pull the intake due to a bad set of gaskets (Fel Pro 1260) which I am replacing with the steel reinforced Fel Pros (1260-S). I am about to put everything back together.

I am thinking of changing my jetting yet again. Currently I am running .60 Idle, .80 idle holders, 145 mains and 205 air correctors. I am also running F-7 E tubes. I am thinking of going with the F-16 E tubes, since the engine is still very rich on the idle circuit. It seems to run fine on the main circuit.

Chuck at Inglese suggested 65 idle, 1.20 holders, 1.70 mains with 2.25 air correctors along with the F-16 tubes. I have read some say that this combination creates a too lean condition.

I have in my possession .60, .65 and .70 idle jets, .80 and 1.20 idle holders, 1.20 and 2.05 air correctors and F-7 and F-16 E-tubes. The only mains I have are 1.45, but I can easily drill them to a larger size if needed.

My engine is a 351W with AFR 185 heads. Compression is 9.7 to 1, timing is 32 deg. My cam is 573 lift intake, 568 exhaust, duration @ 50 is 244 intake and 230 exhaust with 114 deg lobe separation. I live in Clarksville, TN which is about 500.’

What do the experts say about my jetting???

Thanks,

Gun Doc
