I have a 1997 302 Boss w/7.4 Mercs (Not Mags). My wife and I really like the boat. It's Red & Black and Very Clean. We're topping out in the low 60's. I'd like to upgrade my engines without sacrificing reliability. Since mine are not 454 Mags, I've read that Blowers are not a good option. Do I try to sell my engines and buy new ? Where would I go in the Atlanta area for that ? The motors are in excellent shape with only 250 hours on them.

Depends on how fast you want to go? The 454's are worth between $2k to $2.5K each at best on the open market. For that boat you could go to www.1800runsnew.com for some new engines. Not bad pricing. The 540ci is a good option. You will need some performance exhaust CMI, Lighting, Gil. $2K a side for that. 600hp a side should get you around 80mph. Dont forget about props, external steering is a plus at that speed, and someone to remove and replace the motors.

The standard 454's could get a short block rebuild, new hyd roller cam, new heads, new intake, new carbs, new exhuast, new ignition and get you a reliable 450 to 500 hp a side.

By the time you build the 454's up, it might be better to get new engines (warranty). It will be about the same price and the new engines will have forged crank, rods and pistons.

Just my two cents.

The 540ci is a good option. You will need some performance exhaust CMI, Lighting, Gil. $2K a side for that. 600hp a side should get you around 80mph.

Is there enough room to fit that in the hatch on a 302 or to even get down in there with a 540?
