New to Fords needing 460 schooling

Post  460F100 on January 10th 2015, 11:19 pm

Hi. I'm new to the forum and fairly new to the 460. Here is where I start . A 1978 F100 short bed with a 460/C6 3.50 trac loc 9" rear. The parts for the new engine build are a 50k super clean 73 460 from a Lincoln. Have acquired a set of C8VE heads with stainless one piece valves, full roller rockers, 600 lift springs and 3 angle valve job. Also a performer rpm intake,750vs holley and hedman headers. The plan includes new hi volume oil pump and 71 timing chain set up. Looking for a fun street /strip truck to go mid 13's. Need some advice on cam selection and anything I am missing.

You cant go wrong calling one of the vendors on here to get a custom cam, doesnt cost anymore than buying off the shelf and will be a better running motor to boot. The Mad Porter has instructions for porting the cast iron heads on his website if you want todo the work yourself, provided they arent ported already.

Welcome ...
1, you don't need a high volume oil pump
2. Valve springs are not the valve lift limitation; retainer to seal clearance IS.
3. it is much easier to get a 90's and later F.I. truck timing set.

Like Randy said, you don't need a high volume pump, but an oil pan with good baffling is a must.

Thanks for the info. I will be able to get a better look at the heads tomorrow to see if any port work was done. Was told castings were unported . Any experienced idea of what compression it will be with a stock 1973 bottom end with C8VE heads milled 10 thousands for clean up. Have been told anywhere between 9.5 to 10.5 to 1. Not afraid of advice from more experienced people.

That engine should have pistons with an oblong dish .240" deep and about .035" "down the hole".

Given those numbers with the change in heads, the static compression ratio would be around 9.5/1.

Just pulled a head and sure enough an oblong dish with 2 valve reliefs . But at top of bore with a straight edge it held a .013 feeler gauge. I don't know if that is the proper way for an accurate measure or not.

If that is the case then it is not a 1973 engine which had a 10.322" nominal deck measurement or that block has already been decked.
Earlier blocks were 10.300" or 10.310".

You are better off if that is the true measurement; the compression will only be 2 tenths higher.
