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.

Well, I kinda agree with you, 1Gary-----we all do put too much emphasis on HP. Since we all know the old saying "hp costs money, how fast do you want to go?" I think at my age and "needs" for my next build, Ill want something respectable b ut not a real ground pounder. I have been checking out the 4.3 marine engines-----change exhaust manifolds, add some "go fast" chrome and they just might be something to consider.
Originally I was looking at building up a 64-5 chevy II next, but now Im considering a 67 chevy shortbed instead. I think the duece would be lighter and have more "jump" from a 6 than the truck would---but with either, Im looking forward to the "wow" factor of opening the hood on the v6.
