I’ve run a lot of setups and for smaller upgraded turbos the kelford 264’s were just so much better in the range those turbos like. They had the driveability of a comp 272, but made way better power as rpms and boost go up.

We regularly made 1200+ with a stock 6 bolt crank, r&r aluminum rods, and Diamond pistons, in a stock 6-bolt block 3/4 filled.Trying to make big power with a stock 2.4 block is a waste. If you want more displacement run a 2.2 in a tall deck...

If you’re upgrading stud size just go to 1/2” and find a regular arp stud that fits. Clamping force will be about the same, without the 9 month wait.

With only a 16g, injectors, pump, maf translator, and eprom chip for the injectors I ran low 12’s with e85 in my 1g.That was stock intercooler and stock exhaust.Getting setup on e85 will do way more for you than any intercooler and pump gas...

The engines using those studs were made from 1990-1992.5. They don’t sell a lot. And every time they set up tooling to make them, they’re not making high sales volume parts on that machine.

Strangely enough we found the opposite to be true with stock block castings. At low to medium power output the bore distortion from the studs and the clamping of the head are the largest contributor to bore distortion. Somewhere between 200-300hp...
