427 and 454

No problems with either the L88 or the LS7 and using the 850 DP Holley. But both have gobs of HP.

Mark,

Never experienced any bog with ours. It makes you wonder if it was just a defective carb from the start and if a switch to another similar carb would have produced the same results. Seems like you can sometimes chase your tail compensating one fix for another.

Just inadvertantly blew away a detailed response...darn it.....short version is that I COMPLETELY cured my "bog" problem by increasing the #31 squirter to a #37 on the primary side....carbureator diagnosis course 101

Yeah.. I'm starting to think this sounds like that old saying... Don't belive everything you read...So far..with the exception of Kid_Aagain....no ones had any problems.

As far as Kid goes.....Well...You No Him...and what's always following his Vetts...

A #37 Huh.........Ok ..Well if my holley strats to give me problems..it's going right into the trash can..!!! I never really liked Holleys anyway. To much gack inside and they always leaked and blew up power valves.

I'm a carter guy... Simple design...Reliable ..No leaks .. no fancy shmansy jets and vales and other teny weny little parts. I could go on for another page about Holley. It may be a great carb when you get it right ...but to me there's nothing like a simple reliable design like the Edelbrock version of the carter..

OK ..mabe not as good a performer... but I aint gonna worry about bogging and shmoging and peeing all over the intake from a leaky carb...

Was it a Carter?

Was it a QuadraJet?

Hmmmm........................... I've got the info around here somewhere.
