in a month or so im pulling my 500 hp carb motors out of my 2000 32 active thunder and doing a refresh and build up . would like to get about 600 hp out of them and i know it has been done so my question is.

what to use for parts and where to get them.

part #s for refresh and build up parts.

if you have done this with good results id love to know exactly what you did.

thanks for your input

Whipple or procharger!

Upgrade your throttlebody to an ASM unit.

I have a used one never run on an engine for sale in the swap section!! If it ever returns!!

mine are carb motors, and with 360 hrs need a refresh so i want to power them up at the same time.

Even better, I have a complete ASM intake and the throttlebody for sale for the 500

I was kidding with you!!

We have done several of those updates. we use cnc ported aluminum heads, camshaft, intake, modified carb and MSD ignition and you will have 625 HP.

where is the best place to get the parts,, also what about exhaust the stock gill ok.

We have a full kit. And yes we have done them with the Gill ex. It is better if you extend the tail pipes and get the water to dump out the back of the boat at the end of the pipe.

how much is a kit, and what all do i get, as i also will need roller lifters ,bearings, rings, gaskets to refresh as well. i have msd boxes.

also a buddy of mine has 1994 502 mags will my heads cams , roller lifters, intake and carbs work on his and what kind of power increase will he get.

thanks rick

Yes all your old parts will go on his 502. He will end up with the same engine you have now the bottom ends are the same. Call me I will price out a kit 810 3242720
