Whos had engine rebuilt

[ace_800 5,000+ posts]

I just found out I got a extra 389 Tripower engine with my 66 GTO I bought, standards a 335 which is currently in. Decided I'm going to rebuild the 389, but don't know what I should replace with better parts. Ross dished pistons I've been told so I can run the stock heads with pump gas and not destroy the engine. Since the Tripower doesn't like 92 octane with the stock 10.75 compression and that I should run it at 9/9.5 to 1 compression. What else should I have done?

I'm thinking about rebuilding my engine in my V6er. I'm not sure about your engine, but I plan on replacing the pistons, the valve, and overhead rods, and cleaning up the rest and putting it back in. I might bore it up, but IDK.

Also thinking about dual exhaust and manual ******. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif (I hate auto.)

EDIT:: In for read.

forged pistons, cast crank, forged shot peaned rods, lunati cam, port polish the heads. if your looking for performance. look at summitracing.com look up stock specs for the piston size, rod length, all that and match them up.

Pistons won't always make it so you can run pump/unleaded gas, hardened seals in the heads will. Buy some nice flowing heads, a mild cam, and a good intake/carb combo. Are you looking for straight up horsepower, a street machine, or a little power with economy?

A little power with economy, it will be a weekend ride.

You can run pump gas with that compression...you just have to get a big enough cam to bleed off enough cylinder pressure. Ross pistons are high dollar stuff, Keith Black pistons are cheaper (they arn't forged) and as long as you don't run more than a 150hp kit you should be fine. It's all about the combination...the parts need to be matched to work efficiently (don't put an open-plenum intake on a motor that only revs 6k RPM). You don't have to get TOTL parts to have a great motor and have fun.

On that motor, if you MUST use it, definitely get rid of the tripower, it is very hard to tune and set up. Go with a good 4 barrel carb/intake. Before you look at pistons, make sure you get some good heads first, that is where a lot of your power will be. Get a cam to match the heads and intake, dont just buy any old cam based on specs. Also, some decent headers and exhaust. Hooker or Dynomax for those. Look at Edelbrock for the cam/intake/heads. I have had extrememly good luck with my Jet stage 3 Qjet carb. Jet performance takes care of all the factory flaws in the qjet and will even get it set up for your engine. Just make sure to have your top end already picked out. To go really trick, definitely go with an electric water pump and fan, also will gain you some horsepower. get one of the new distributors that let you handle all of your timing adjustments on the distro with little dials.

electric water pump seems unnecessary, I dont think for the price it's worth it.

Yeah, bore it out.

Same thing.

See I'm not trying to do all that, I want to keep it at least original parts. I'm not going to be tuning the Tripower at all. This is going to be a weekend driver, not a drag. Exhaust and headers i don't want to do, deffinitly no electric water pump. Switch out a few parts with the Tripower, rebuild and use that.
