Exhaustsystem for stroked 351w

[Pappa Keno]

I was wondering if anybody knows if the exhaust holes are the same size an position on a ford 289sb as on a ford 351w stroked to 427 cui with victor junior heads, so i can swap my engine without buying a new exhaustsystem?

Thanks

Nope, not gonna happen, 351 block is taller & wider ( c/l crank to deck is : 8.20"-8.21" 289/ 9.48"-9.50" 351 )- new set custom built for your new combo is the only way---427ci is probably going to require larger dia pipes as well and check also for raised ex ports on your heads. Safest way is to fabricate them on your motor & in your car.
