I Need Engine Experts! 340 Roller Lifter and Pushrod Issue

Newbomb Turk said
First things first, go to b3racingengines.com and get ahold of Mike and have him hook you up with a kit to correct the geometry.

Then you need to relieve the heads where the pushrod passes through. Even a 5/16 pushrod will hit with hydraulic rollers.

Thanks for the suggestion. I will contact him on Monday

Another thing worth mentioning, most over the counter roller lifters will push the oil band up and out of the chamfer at the top of the lifter bore on an LA block. Check this before installing the intake. Run the pump with a drill and roll the engine over through max lift and see if oil gushes out the top of the lifter bore.

Great suggestion - I will check this to make sure. Visually, it looked OK and not too high, but a quick check by running the pump is easy extra insurance.

Look at the push rod angle difference. Left is the tall standard roller lifter. On the right is a shorter lifter with an offset intake lifter.

Thank you, and this is what I was looking for. Do you have a manufacturer/ part number of the smaller lifters?
