Claimer engine

Theirs a michine shop here in San Antonio that can build me a claimer engine cheaper that I can mail order the part for.Do you think they use substandard parts? They also say that it will be blue printed.Is blue printing where everything is measured?It would be around 150.00 cheaper than what I could do.Is this a good deal?

Everyones labor on these deals is usually the same amount of time for the basics; its attention to detail and careful selection of parts where you find the winners.
$150 is a lot; so unless he has a warehouse of cores...I doubt you're getting quality parts. If all you want to do is knock around the track; sure buy it. If you want to be competitive; you need to build a better system than the average guy...more research, more doing hand work yourself to stay under budget.

Think of it this way; hes either doing 1.5 - 2hrs less work (@ $75-100 per hour), hes not charging you for some parts, or he's using cheap parts...OR he is new and needs the business.

For a cam; Id call Mike Jones and have a link ready to let him read your rules

You get what you pay for, period. Wanna "cheap" engine? It's gonna have cheap parts...

As for "blue printing"... This is among the MOST abused terms in engine building. No, it is not "measuring everything". We (engine builders) call that "assembly".

Consider that the engineers, when designing an engine, draw up "blueprints". Today, they use CAD/CAM, but the result is the same. In those drawings are specifications. Along with those specs, come "tolerance levels". That is, how far "out of spec" one part can be in relation to another and still be "usable". There are different levels and types of "blueprint" where engines are concerned.

In most cases, a true "blueprint" is far too expensive (labor-intensive) for a general "rebuild', or even a mid-level performance build. What we do in this case, is assure all comparitive dimensions are "equal". That is, piston-to-wall is the "same" across all cylinders. Valve stem length is "same" across both heads. Valve seats are concentric and equal in diameter. Decks are "square". Strokes are "indexed" (equalized). Bearing clearances are "same" and "in spec". And so-on.

A "true" blueprint involves all "new" parts, and modifying them precisely to achieve the EXACT specs (across the entire engine) as laid out by the engineers. While bore sizes and journal sizes may be "adjusted" to fit within sanctioning rules, an engine such as this is VERY "involved". It takes approximately 40 man-hours to "blueprint" a NEW GM "Bowtie" SB-2 block for a "cup" car. And that's JUST the block! Those guys do what we call "chasing a thousandth". The result of their efforts are 800 HP engines that rev over 9,000 RPM for 500 miles... Not bad for "pushrods"... (:- But this can help explain WHY a "cup" engine costs more than $40K.

FWIW

Ask what he does and uses in the engine. I know a guy around here that does cheap engines but he uses some used parts, they run real well though. If he can supply references that's even better.

It has occurred to me to ask: Do you know what a "claimer" is?
