ATTN R302 owners
 

ok after researching the cost of putting a stroked winsor in my truck and then getting it tuned for my supercharged application I've decided on putting either a 331 or 347 in my truck with a new B50 or R302 block.

The R302 is a siamese bore so in other words it doesn't have water between the cylinders.

Do any of you R302 owners have trouble with running hot on the street? I will be street driving this truck as well as abusing it in the sand dunes where I won't have a whole lot of air flow.

Any comments? I really would prefer the R302 so I could get 1/2" head studs and hopefully have an indestructable lower end. But I don't want overheating problems.

Thanks

Yes. I don't have one, but that is why. They have a problem with overheating if used regularly for extended periods of time. That is why so many people are looking for old A4 blocks instead of using a new R302 in a street/strip car. They are great for all out drag cars though. They will handle insane amounts of power. I was going to get one until I heard of this problem, that is why I also am looking for an A4 bloch instead. Light Em Up!! http://www.mustangworks.com/interact...oard/smile.gif
