SB2 in a street car

[ArisESQ]

Has anyone here run an SB2 motor in a street car? Any experience with this?

i was close to buying one from a nascar "chop-shop" think they were called excessive motorparts or somthing, but was advised against it here on this board because most of the heads out there are test heads fron cup teams that are not to their liking, and really is built to match a specific intake and run restrictor..... but if you can find a whole setup on racingjunk you should be good, just be suere to get a set of matching headers!

i have seen some built for pump gas, 410 all aluminum sprint car engines on racing junk that would be a good ticket... but i went with an LS1 and a t70 turbo as it would make comparrable horsepower, in a more streetable way-.. at half the cost..

The have a 69 convertible that they built in 1999 that runs a SB2 motor. They took it on a couple of power tours.

The way I understand it is the best way to make those motors streetable is to make a stroker motor. Jimmy Johnson's 67 camaro is running an SB2 motor. They are taking a cup motor and lowering the compression and stroking it out to 400+ inches.

www.racingjunk.com is a good site for that kind of stuff. Another good option if you are looking for that style of motor is an 18 degree 9:1 busch motor.

I have a friend that has one for sale complete from oil pan to carb with a 5 stage dry sump. Kinsler individual runner intake and 2 new turbos.

One thing to be careful of with these motors is oiling. The expectation was that these heads (SB2 or 18 degree) would be used with dry sumps - if you're using a wet sump, make sure you restrict oil feed to the top end so you don't accumulate oil in the heads over extended high RPM pulls, which will starve the bottom end.

Mark Stielow built an 18 degree motor for his Thrasher project about 7-8 years ago, and as I recall he toasted the bearings at One Lap of America because of the oiling problem.

has an 18 degree motor as well

One issue usually associated with the used Cup engines is that the factory engine mount bosses on the driver's side have been milled off for dry-sump pump clearance which makes it a necessity to use motor plates. A friend has bought probably a dozen used SB2's from RCR and they were all this way.

Another issue for street use is that often the stock oil filter provision is gone too since they run dry sump with a remote filter.
