1970 lt1 deuce pistons

[rszmjt]

Factory LT1 pistons have a .100 dome hite and were forged pressed pin, 302 has .200 dome hite and were forged as well with floating pins.

As noted 302 pistons have a different pin hite location in piston due to only 3” stroke, LT1 has a 3.48 stroke crankshaft, rods are the same length at 5.7”

Original LT1 was a 4.00” bore as noted, it makes sense to measure your bores for wear and if needed bore to .030.

Aftermarket L2304 are available in .030 & .060 only, some company’s make a cast type LT1 piston in .020/.030/.040/.060

If your motor did not have forged pistons originally you should have it rebalanced as piston weights are very different between cast and forged.

I do have a set of std & .030 I’m thinking, pm me if interested.

Hope this helps.

Mike.
