Ok guys heres the deal...
I have a friend who writes for a national mustang magazine. When I told him I was building a 408, he had a suggestion. He talked to his editor about doing a story on a 550 HP pump gas motor using a factory 351 block. He got the editor's buy in, and he instructed me to look for a block ASAP. I would like to use a Dart/Manowar/Sportsman block but it's not in the cards.
There are some fringe benefits when doing a motor build for a magazine article. Namely FREE PARTS!!! We have arranged to have a reciprocating assy, heads, cam, intake and carb set up contributed by advertisors so they can get their name in print.
Back to my original request, it really doesn't matter if I use a one pc. seal or two but I heard the two pc. units always develop leaks. If the older blocks are truly stronger, I'll add a vac. pump to the engine and it should resolve the problem.
Thanks for all the replies! I'll keep you posted with the latest developments and when the article should be published.
