Yeah youre going to loose some throttle response with a 340 intake. Youre probably best off picking up an Edelbrock Performer 318/360, its designed for 318 ports, plus it will save some weight.
Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

I too, have seen too many leaking ones to be a lover of them. I do notice though that the small block ones do seem to hold up much better. the heat coming off the big block engine was too much for this carb.

Hi Scott. I would get a square bore 318 one for the ports to match. With the lack of cubes you wouldn't want to have any mismatch of parts that would hurt you if you can help it.

Well these things were warping and cracking within a very short time of being new so it didn't take 30+ years of deteriorating to do the damage and warp and crack the bowls. There were more bad ones come in than good for repairs/replacement. If you were lucky and goe a good one they were great but-------------- PS: I am not a lover of Holley double pumpers on the street either. But over the last 40+ years have had a lot less problems with Holley carbs than Thermoquads. If you like them fine use them. If you find a good one.

Thanks Robert. Is the mismatch what would cause the loss of throttle response with a 340 intake that GTX Matt spoke of? Could any of that be salvaged by grinding the ports to match the manifold?
Thanks

I've run a 750cfm 3310 vacuum secondary Holley on a number of different cars/engines/setups that are driver type vehicles. The only time a power valve ever blew was when the car wasn't tuned right right after a rebuild. Oh yeah, at least I can get parts for said Holley when/if I need them.... ...but I usually don't. Where, again, can you find a new main body for a Thermobogger? While your fixin' I'll be

The factory 318 4 barrels used the 360 intake manifold. I wouldn't hesitate to use the factory iron manifold on a 318. The factory 340-360 manifolds were a great design, many aftermarket manifolds show a power loss in comparison.
