Thanks again for the information guys,,,,,

You should be in around 225HP maybe 250HP which is comparable to a 283 4bbl Chevy. Actually if you keep the hood closed most will believe it is a 283. I picked up a dirt cheap 92 Astro van 2wd with the 200HP "W" engine (CPI inject was shot putting a carb on anyways) and 700R4 trans for my project. I can use the front calipers which are the same as the late 80's Camaro, steering column, hydroboost brakes and yes the front rotors 12" 5 on 5" bolt pattern, with a little machining the MII spindles will take an A3 outer bearing and an A13 inner bearing. By using a right hand axle on the left side I can narrow the 7.5 10 bolt to a usable width, all this on a budget. Sorry getting off course.
