I started restoring my dads old truck over a year ago and it has dragged on due to parts availability and other projects, it is now a priority to get finished and running for spring.
I have a 1979 460 shortblock with stock pistons, new rings, bearings, a summit 3500 cam, edelbrock pro-flow 4, and 85cc AFR heads with inner springs pulled for the flat tappet cam.
I used the summit cam because it was on my shelf collecting dust (204/214 degrees @ 0.050") and it has lots of valve clearance. I was going to run it for a year then build a stroker but just found out either my pan gasket or rear main is leaking so I have to pull the engine (found the leak before finishing the install, never even got the starter on) and I don't know if I will ever get around to the stroker so I am debating a bit more camshaft (Lunati VooDoo 10340702 219/[email protected]") and calling it done. From reading CarsByCarls old posts I should be safe up to about 225 degrees for valve clearance but I will check and if I need to cut valve reliefs they should be shallow enough for the factory pistons?
This won't be a strip truck, just a fair weather farm truck with a slip tank and maybe haul an old green tractor to a show now and again. 2 wheel drive F250, C6 transmission and 3.55 gears.
Will this cam be to much for towing/street use with relatively low compression? Will the stock pistons handle valve reliefs? If not are there non-custom 460 pistons available with AFR notches or just stroker pistons?
Thanks

Are the AFR notches in different spots than others?
Here's a link to Summit to pistons with notches

good luck

Yes they are.

In between the standard valve location and the P-51 / SCJ...
