Crazy.. i actually emailed howards and was like.. is this normal? "Just put in at 103 like it says" ok.....Worst I had seen was 15 degrees off when dot-to-dot, and it was not a tooth off. That was on an Oldsmobile 455 with unknown brand timing chain and cam?
Haven't seen a Mopar off that bad.
I have had good timing results with the 440 Source 9-way timing sets and Comp cams usually being correct (within a degree) when installed dot-to-dot.
My 58 Belvedere would only do 108. It had the 318. What did this one have?You see that car.....
It weighed two tons & got to a top speed of 118 mph...with a TINY 2bbl carb. It had great acceleration getting to 118 mph....
