You see them in the magazines, the way overpriced self aligning roller rocker arms that have little washers on the ends of the roller tip to keep it centered on the stem of the valve.While I find it funny that people would rather have some small washer rather than a thick 1/4 piece of steel guiding their v...

Having a traditional LT4 intake manifold side by side with the Edelbrock LT4 Air Gap reveals a lot in terms of design. For example the inlet holes on the air gap are much larger. The air gap design not only allows for a cooler air charge due to better heat dissipation, but it also makes for an aggressive in...

Well everyone knows that every year Federal Mogul just can't help but to drop the ball when it comes to 350 parts. Sure Federal Mogul aka Sealed Power, Speed Pro and FelPro make some damn good stuff! But why is it every year some part for the 350 always seems to be on back-order until the middle of summer...

As the years go by more and more we are finding people whom come to realize their 5.7 liter LT1's are really 4.3 liter L99's. This sort of thing has been going on forever, since way back in the day when the 350 had a baby brother 305. Its very easy to spot an L99 from an LT1, to do this you need only look at the bac...

One of the worst things you can do for a performance engine is to install factory or torque to yield head bolts! These bolts are crap and saving money is about the only reason I can see that GM went with them. Scrap the factory head bolts. Use ARP head bolts. Be sure to put orange silicone on all the threads a...

The answer is NO. The LT4 manifold is diffrent and will not bolt on a stock LT1 engine. I have attached photos for the MEMBERS only so you can see for yourself first hand. Enjoy the photos.
