Hello,
I'm currently doing my best to spec a 331 stroker from a 1971 302 block, whilst researching this subject i have read (more than once) that the standard 15426378 loads up the front main with the first 2 strokes being above No1 main and should be avoided. Even though the 351 & later 302 13726548 firing order loads the rear, the block handles it better.
How true/proven is this that it causes premature wear on the front mains??
I am not looking for mental HP. 430-450 would be nice, so am hoping its not an issue for a normally aspirated engine or should i avoid 1542 order cams
Cheers
