I am running a 427 (512 block, 840 heads) with an M-22 in a 68 Camaro. The car is used for nothing other than driving around (no shows, could see occasional strip use). That being said I am thinking about doing a new motor over the winter. The question is would it be best to rebuild what is in there? Or sell the old parts and go with more modern components? If I go with newer parts, which ones? This is not an unlimited dollar project and the only other consideration is I want it to look like 1968 under the hood not 2006. Thanks for the help

I would say rebuild the one you have. The 427 in there should run for many miles. You have an excellant foundation for a nice streetable 450 HP engine.

If it were mine, I'd stick with what's there. 'Course, I'm partial to Old Stuff! https://www.yenko.net/ubbthreads/imag...mlins/wink.gif

Hey, watch it! I'll yank your Credentials! https://www.yenko.net/ubbthreads/imag...ns/naughty.gif

I have had 3 motors in my 1969 Camaro over the last 2 years. The first was a mild 454 that came with the car that ran good but was boring. The second motor was a crate LS6 454 that I built to look like a 396 L-78 at first glance but I wanted more horsepower. The latest motor is a Bill Mitchell 540 that cost around $10,000 to buy and I spent a whole bunch more to make it work in my car. I had to tweak or upgrade almost everything from different hoods, motor mounts, fuel pumps, radiators, fans, brackets, fan belts, headers, exhaust systems, clutch set ups, fuel lines, valve covers and air cleaners. It has been a steep learning curve and I can still find things that I want to do over again because of something I learned along the way. The quality and the horsepower for the dollar are hard to beat with the Bill Mitchell crate motors. But I have yet to go full throttle in the car because I am afraid of breaking something on the car or damaging the car. My problem is that I do not want to modify the car past the point of being able to put it back to stock some day. There is such a thing as too much horsepower in a stock frame camaro and it can get very expensive very quickly. I have had GM high performance crate motors in the past and I always felt that the motors never quite met my expectations of quality and performance. I would recomend that you stay with the motor in your car and build it. If I had to do it over again I would have stayed with the LS6 454 because it was better matched with my car.

Hey Bill, Why would you NOT rebuild the parts you have already? Those parts are hard to come by. Keep what you got and freshen it up. JMO. https://www.yenko.net/ubbthreads/imag...iggthumpup.gif Sam

OK, Thanks for the help. I was actually thinking that I could sell what was in there and go with a crate type motor and end up ahead of the game both on $ and performance. I think Mark put the disadvantages of that plan in very good perspective.
