Critique this combo - 318!
Nuthin wrong with hypereutectics. Almost EVERY single time you hear of somebody havin a problem with um it was operator error. They have VERY strict top ring gap specs and as long as you adhere to them, you will be fine. I always run mine by adding the "towing" spec and the "nitrous" spec for their top ring gaps together. Usually end up over .040" top gap, but it works well. People who spew bad things about KB pistons have either not used them, not used them correctly or seen or heard of someone who has done some of both. They are great quality pieces, but like anything else, you have to follow the deestruckshuns. Now, the only other "problem" I see with your combo.......the carburetor. And guess what? That's comin from a TRIED and TRUE Thermoquad guy. As far as Im concerned, there's not a better carburetor on the planet.......BUT, it sounds to me like you're leaning more towards a race car than a street car. That said, I would do one of two things. Get the RPM with a good HP Holley of some sort....Demon....whatever......OR go with the 440 version of a TQ and trick it out some. You're only talkin about 50 more CFM.....AND you're talkin about a pretty hot 318. It'll take it just fine. the TQ is a really forgiving carburetor. Some may say it'll never handle the 850, but I got news......it will and then some. You're gonna be talkin about trap RMPs over 6K. That's a lotta RPM. It's gonna need a big carburetor. Now....one last bit of advice......and I HATE DETEST ans DEPLORE carburetor adapters.....BUT....that RPM intake is a real gem. You wanna try sumthin that I bet will REALLY work? Slap an 850 TQ on top of that RPM intake. The adapter in this case will act as an RPM extender and probably give you another couple hundred RPM on the top end. Yer gonna need it. Other than that, your combo sounds great. hell, it's great like it is......you just asked and those are "MY" opinions.
