I've used the Holley blue gaskets and reused them many times with jet changes. I did have an issue a while back where the initial installation was fine but subsequent re-used caused a leak, apparently after the gasket was initially compressed. Something in, on or around the carb was keeping the...

Nothing but what is recommended by the piston manufacturer. They have to be the correct material and precise design, tension & measurements.

Rotate the engine bit-by-bit and reprime. Gotta line up the passage holes. Ideally, prime it while somebody else rotates it manually.

I would suggest a regular header bolt that has a 3/8" hex head and built-n washer for all of them.

273/318 main caps are physically shorter than 340 main caps. Less "meat" and shorter bolts.

I have plates and the newer nipple/stud with internal 3/8" drive to install it. Tried to PM but your mail box is full.

If I remember correctly, Champion plugs with a "C" on the end (i.e.: N-10YC - more search options) were an upgrade from the originals and had a copper core, or something like that.

May be related but I read somewhere that cranks 360 cranks with CFD cast into them were stronger than the ones with AAWJ and that CFD represented a GM foundry!

As mentioned about Champion plugs, lower # = lower heat range. Some other brands follow that pattern while others are lower # = higher heat range. Gotta check your brand. FWIW N9Y were originally for high compression 340s and N10Y were for 426 Hemis. (I believe Champion 61 & lower were...

It may be code for the foundry that cast it. Certain 360 cranks & heads have that cast into them also.

Just in case.....it's also a good idea to hone with deck plates to simulate any bore distortion that the head bolts may cause when assembled. Some people go so far as to use the same head gasket that goes into final assembly as well as bolt on a head or deck plate on the other side and...

Agreed! I've gotten at least a tenth better performance going from a 3310 750 vacuum secondary to a 4779 double pumper after spending time tuning both on the same combo.

Regardless of brand, many people leave out the front & rear end gaskets and just use silicone. Some end gaskets squeeze out and others are too thick or hard and don't let the intake sit low enough. Make sure the intake lines up properly with the side gaskets in place. Depending on any other...

It depends. One has to determine what .15 seconds in the 1/4 is worth - what it takes to achieve it and what it actually costs in time and money. A lot of the "worth" depends on the rules you race under. The more restrictive the rules are, the more difficult it is to make "legal" changes for a...
