Hey gents,

Stumped on this one. Replaced my Edelbrock with 4BBL Holley (4160), at the same time, replaced exhaust manifold gaskets with the ones with smaller holes. Now, car seems to surge (slow/fast) every 3-5 secs.



Any suggestions or places to look?



Thanks in advance for your help.

Sounds like a vacuum leak.  First place to check are the gaskets under the carb.  If you have a spacer under the carb, insure that the gasket seals adequately there also.
