Has anyone ever tried to install a 351 Ford Windsor instead of the customary 302? I know that by having the engine deck taller it also increases the width. It would be kind of neat to see an MG with a fuel injected 351 from a Ford Lightning. Not to forget all of the available stroker kits that could take it up to and pass 427 C.I.

And as a small reminder, Ford is still a government loan free company (LOL)

Okay, gotta give 'em credit for that!

And to think, some of my friends tell me it's possible to put "too much into one of those little cars."

True, but the real beast is the Chevy LS 1 and it still is fairly new technology, I'd say that it'll be a handful for any MG owners to handle.

Ford spent one billion dollars developing their OHC modular engine but as with most overhead camshafts it ends up too wide at the top end. It's even worst when you try to use the dual overhead cam (32 valves Cobra). It's not the preferred power plant of street rodders. Although, it looks great in a 1956 Ford P/U.

Personally, I like to stick with the rules of front/rear weight distribution ratio when selecting a power plant.

It is about 1 1/2" taller and wider than 302(5.0). MGC hump hood and mount low as possible. Also the 94-96 F150,94-97 F250 5.8 were roller blocks. If built and stroked will give the LS motors a run for the money. Maybe Pete will have a modified kit for one?

Seems like that's just a little too tall to work well in a MGB.

I've seen pictures of an early roller 5.0 that was bored out to 4.1". I think the early blocks (1985, 1986) were cast with thicker cylinder walls and could be overbored this way. With a 3.25" stroker crank, that gives you 343 ci/5.6 liters, and with the 3.4" crank you get 359 ci/5.9 liters. With a roller cam and SEFI, that might work out well.

Hi there,
The 289//302 blocks are recommended to be stroked with a 3,20" crank out to 347" "Street Fighter" with
Edelbrock heads which are recommended as they are meant to suit the motor of a 4" bore..No amount of working
the standard pollution grade heads is really an advantage if you want about 360 HP. A Good 275* cam goes well
with a Decent 600/650 cfm carby. Your Money and your decision..Good luck with the project..Noel
