One more thing, the 302 is tight in the engine bay so I wouldn't advise a Boss swap unless you like raising the engine to swap plugs. LOL. I have seen a 351C in a II but it looked as if it were grown in there.
The 68' 302 wouldn't be a BOSS. The 302 BOSS motors came with Cleveland 2V heads. A standard 302 would fit with no problem, but you would need to purchase the 75-78 302 oil pan for the Mustang II. Also have to stay with a lowrise intake unless you plan on a large scoop. Swapped my 4cly for a 302 back in the 1980s. Sold the car years later, but lots of fun.
What height scoop would I need for the stock intake? I want plenty of air, because I'm installing a 600cfm Holley 4bbl.
I ran the Cobra II scoop and cut the hood, but mainly ran the lowered base air cleaner. Still ran a 3" filter. I ran an Edelbrock F4B intake and a Performer intake way back when. Would show a few pics if I could figure how.??? Just make sure you have the right oil pan or motor will not drop down.
i assume the OP is talking about putting a Boss 5.0 with the DOHC cams etc not a Boss 302 out of a 1969-1970 mustang?? esp since he said it comes with a 6 speed
well i guess we'll never know lol. fwiw a 302 with a performer rpm intake (non-airgap) and a holley 600 needs a low profile air cleaner to prevent from hitting the hood.
Didn't a few of these cars come with 302s from the factory anyways?
I'm sure the new 5.0 would fit in there since that car doesn't have shock towers...
