Hey...looking for others' experience and/or expert opinions...My car is a 1984 Camaro, 2.8 V6 2bbl, 700R4 trans, 146,000 miles. I took the car around the block tonight, after letting it sit for a few weeks (it hasn't seen much driving this year)....right after I got it home, I kicked the gas a couple times--it wasn't revving up normally when I drove it---and then I heard it knock. I listened to it for a few seconds and then shut it right off. I know you can't really be sure without tearing the motor down, but do you think that the crank and rods are going to be wrecked? How much should I expect to have machined for repairs?
