I was told that all I had to do was get 96 jugs and pistons to convert. Is that it? Worth it?

I could be wrong but......I think jugs and pistons only get you 95". I think you would need a crank also.

You can go 95" or 97". Don't know if you can use 96" jugs or not, but if you're going to get the most out of the big-bore, you're going to have to also change cams. Are you carb'd or fuel injected. If fuel injected I'm not sure if you'll need a bigger throttle body or not. I doubt it, but I'm not sure. I would also think that you would need to raise the compression a little bit, but not positive about that either.

An 88 and 96 have the exact same size piston,the stroke is shorter on the 88.
A 103 piston will turn an 88 into a 95,a 107 piston will turn an 88 into a 98.
Parts and labour are roughly the same if you go to 95 or 98,so I would go as big as possible be because the finished cost will be roughly the same

the 88 can be converted to a 96" at GREAT expense with marginal results- not a good idea.

so the 96" parts are NOT what you want...the 96" is the same "bore" ( cylinder diameter) as the 88"

The 96" has a longer "stroke" than the 88" which is where the extra 4 inches per cylinder comes from.

from an 88, the 95" is easy and popular ( and is the same process a 96" would use to become a 103")

a larger diameter cylinder and matching pistons are swapped in for the stock.

the larger the bore, the more than the piston can "rock" off center ( as the piston has a pivot point which attaches to the connecting rod) so a very wide bore can wear faster and the cylinder will be worn by the piston until in is no longer a cylinder with straight sides, but bulges out in the center ( internally).


so the 95" is easy and a good idea.

when this is done the heads are removed from the motor- this is a good time to have the heads re-worked for better flow.

and a performance cam set.

this will give reliable power of 75 to 80 horsepower.

vs the stock 55 HP of the 88"

Yeah I plan on doing head work and cams plus a dyno tune
