- 1965 Mustang 347 stoker 5 sped od 8n in.276 rear
Purchased from blue print engine off of JC pony site.
Started buying a 331 stroker with standard pistons in a 40 oversized block.
Went bad and they sent a replacement.
It gaulded 3 cylinders and fowled plugs.
Then they sent a 347 stroker.
It fowls plugs real black and uses a qt. oil to 150 miles.
Blue print said intake gasket leaking.
Change gaskets 2 time and intake one time.
Same problem then they said rocker arms stud need sealed.
Sealed them and did help on no 1 and 4 and 8 cylinder oil fowling.
But real black plug fowling on no. 4 and 8 cylinders and rest just black fowling.
Blueprint said gas fowling plugs.
Has had 2 Holley duel pumper inline 650 CARBS.
Has had 3 Edelbrock carbs 2 650 and last one 550 thunder 1802.
Also on last thunder was jeted down to as lean as I could get it without missing out on pull.
Thanks for any help or ideas.
Also was told by 5 mustang owner the 331 and 347 engine had a oil ring problem after the 65 347 blowed his doors off of his new Mustang.
