1967 Barracuda Formula S 383 daily driver build
Well I learned a lesson on this one. I had done all my measurements when I first built the 65 block, put light weight springs in & checked the clearance, checked the degree of the cam to make sure it's per the cam card. I didn't measure anything in this '68 because I figured it worked out good with my timing set-up. The 65 was the first engine I've put together & this is the 2nd. I should have went thru all the steps in the big block rebuild book I bought when sticking this 2nd one together.
So let's get to it, I got it all buttoned up in the car & fired it up, it didn't bust right off & I turned the distributor got it to bust off & revved to about 2500 because I was thinking to get it up in rpm like breaking in a cam. It made lots of noise & died. Cranked it back up & it just spins really slow, not nearly fast enough to fire.
So the damage - the intake push rods are bent, intake valves are slightly down when you stick a straight edge along them (bent after disassembly) & the pistons have dings.
So the issue was the lower timing gear, it has multiple keyways & each keyway has a mark then there is a corresponding matching mark further out on the gear. I lined up the cam gear dot with the dot on the keyway for 0 degree but I should have lined it up with the outer 0.
