Slack when accelerating

Good morning. I reciently bought a 69 Big block, Muncie with 12 bolt. Whiile crusing at idle I accel and there is a rocking motion from front to back. It is a springy motion with rigid stops. ( best I can describe ) Where should I begin looking?
Thanks so much for any help! Wade

Re: Slack when accelerating

Sounds like you are describing surging or may lugging the engine. It could be as simple you just need to downshift into a lower gear to not lug the engine when you accelerate. It could be a surge caused by a lean off idle cruise condition requiring jetting up the primary side of the carb.

Re: Slack when accelerating

Thank you Dennis. To me it just felt like to much play in the rear end or somthing like that. No issue until I give it a thottle amd then let off.

Re: Slack when accelerating

spring bushings shot?
that will cause the herky jerk.
specially if the bushings are OEM rubber.
also does the car have sub frame connectors????

Re: Slack when accelerating

Might seem like the obvious - but are your shocks in decent shape? Sounds almost like you have lost much of you compression damping in the rear and are bottoming out quick then the spring rebounds.

It doesn't look like he's been back online since Aug 8th. I don't think he's ignoring the question. He probably hasn't seen your post.
