Who builds the best late model motor???

[rc24]

HAHAHA This is just Like Chevy Vs Ford.

[buster83]

there is some top candidates but saying who is best and the most reliable is catch 22 question there i a lot more to racing then just the engine.but these 5 Cornett,clements,hatifield,jay d$ckerson vic hill should get u there.

Find someone you can have a great relationship with, not just be a customer, take your money and show you the door deal unless you really know what you want, can give the builder the specs, have them build it then you maintain it on delivery.

A lot depends on you. A great engine builder is only as good as the guys who manage that piece week in week out and at the track. If you don't have the technical know how to get the best out of your engines and keep them tweaked up and running to perfection, get a crate engine and go crate racing and learn basic engine setup and maintenance.

The less sophisticated the engine is, the less knowledge you'll need to get decent performance out of it. And it will be a lot less expensive to replace or repair if you mess something up tweaking on it.

My personal opinion on engine builders is they are all good, but how much their reputation is going to thrive or suffer with your results is going to be a factor in the quality, attention to details, service after the sale, information they will share with you and price you get from them.

Ford - Andy Durham
Chevy - Clements (they do the head work for several of the other builders)

Eagle racing engines were the top dog in the 90's as far as drag engines were concerned they done some very good work for me back then .

Rumley! Maybe the others in previous years.

I don't think you can qualify Mr. Leroy as a builder. If its true what some are saying, he is just an assembler. No doubt it takes special skills to assemble a race engine, but that's only a part of what a real engine builder does!

Ford - Andy Durham

Was wondering when someone was gonna mention him.

Assembler is defined as a person who assembles a machine or its parts. Obviously Rumley knows what parts he needs to build a motor.

Probly......but I bet it has more to do with Mr. Clements parts list!

Well, there are machinists and there are assemblers, then there are engine designers. Unless your developing your own port profiles and matching them to the other parts to make a predictable torque curve, your not a full fledged designer, machinist, assembler. I'm not sure, but I believe some so called engine builders work with a head profiler. I know some of the NASCAR teams do. It's just hard to be good at everything. There is a lot of tech in every part of a racing engine, they pick these parts from specialists with expertise. That would make all of them, so called assemblers.

Calling Leroy just an " assembler" is like calling Van Gogh just a painter...........

[cdustyr1]

sometimes better to go with a local builder

A lot of time the local builders are at the tracks if there are problems they can help get them fixed during a night of racing, also they have access to other business partners to help track down a needed part that can sometimes keep a night going that would otherwise ended early.

I don't know Leroy, but I'm guessing he farms out the machining, as the cost of owning that equipment for just your own engines, would be expensive. He is probably working with a head porter as a 5 angle CNC machine costs more than several years of engines and is worthless without a flow bench. He is old enough, that he could know what he wants for a profile and flow and dictates what he wants, but even people like Hendricks have people do their R/D work. He is probably buying pistons, valve train components, crank, rods and blocks. So at most he would be a designer / assembler.

This is not bad mouthing him. There just aren't any engine builders since the 50s. Tech put them out of business. The last time, I saw someone make their own pistons, was 1958.
