well, I think you mean that they're low horsepower- not low torque. And, I can't find anything on mercury's site about using the 502 anymore.

I just found out there is a guy that lives about two blocks from me, who owns a '67 Camaro SS/RS he bought new in '66. It's a resto-ored car with...get this...

...a late model 8100. I'll be going to check it out this weekend so I'll be sure to get pics of his install.

I haven't seen where Mercruiser is using the 502? Only been seeing the 8100 in the spec sheets I've looked at, but am no boat expert by any means. I've been looking into runabouts/ski boats and seems to be the high end available engine. I've driven a 3/4 ton pickup with the 8100, and was very impressed. I think this is a dynamite idea, good manners, decent gas mileage, reliability, and brutal grunt when you need it. The theme doesn't really jive if you need a massive cowl hood though.

I've already got the cowl hood, and pics would be great durango. Also, anything he's done or any numbers he has for the engine or quarter times would be great.

The 8.1 would be great for a low rpm highway cruiser. TW, I meant low end torque.
Merc had offered the 502 in 390, 500, and 525hp versions. The 502 is also the block used for their 575, 600, and 700 hp supercharged motors. And the tall deck is the block in their 900 and 1075 hp supercharged motors. Not sure what they're ofering this year, but almost all of these are still available from boat dealers.
The 496s are only offered up to 425 hp and operate at a lower rpm range.
I guess if you want to tow, get a 496, if you want to race, get a 502.

I will be getting some measurements too as I'm wondering if the 8100 will fit under an L88 hood, and if the accessories can be modified to fit between the A-arms if there is a clearance issue.

I have seen two different accessory configurations, and one looked like it would fit just fine, and the other did not.

IMHO, a Corvette needs a horsepower engine, not a torque pig. They're light enough that you don't need a ton of torque to get 'em moving and it can actually be a hindrance since it will make traction an issue - and if traction isn't an issue, your IRS may be. I think these would be great for 4000lbs Chevelles, Monte Carlos and trucks but Corvettes scream for higher rpm horsepower - at least mine does!

The whole reason I'm looking at the 496 is affordability and fuel injection. If I was looking at racing- I wouldn't go with a 502, I'd go with a 540 or a 598. I'd definitely change the cam to begin with, and then later on maybe some heads, as money permits. And the higher rpm screamer would come later.

What kind of prices did you find on the 496. I have not seen a crate version for sale yet.

I think I'll be able to get a 496 with wiring and computer for just over 2k from a scrapyard

No pics from the guys Mustang. Turns out it's an old 496, not a new one. Nice project car though.

I have priced some complete motors and found lots in the $2500 range so that's a good deal.

Yeah, I've priced it but need to sell a gtp I have or work out a trade in order to afford it. I may just part out the gtp.
