Re: Question for those who build and sell engines

I put it in writing they needed to change the module or no warranty expressed or implied on the work I looked at that was well and the installer did his work correctly. The boat owner was not completely honest about the deal either. Had another guy that flashed the module telling them they did not n...

Re: Question for those who build and sell engines

You can have NO WARRANTY all through the work order and that still does not prevent you from ending up in court. I had an experienced marine shop contract me to do a small repair on a ford 351 W which used the Gt-40 heads from factory. Now they use a different valve size then the regular 351 W and d...

Re: CC ing chambers

nascar officials commonly use that Katech Whistler thing for checking compression, which brings up another point (pardon the pun). Be cognizant of how the officials will check the compression ratio. Carefully observe their method for checking and compare their results with your own measurements. Un...

Re: Question for those who build and sell engines

I have done the part time at home stuff for years. Been fairly lucky I guess. Only remember one problem. Guy overheated and cooked a new engine. Water pump or radiator problem, can't remember. I took it back in, disassembled, paid for needed machine work, and handed him back everything in a box. To...

Re: Cams

I am with Mike J and Walter Comps mass marketing Technic's from the past was to cover every hot rod and race car publication with their hype technical BS making them sound like they are the kings of the cam world.

Re: CC ing chambers

When cc'ing things that are for class racing rules the most common thing guys forget is the volume from the top of the piston to the top of the top ring in their final measurements and loose a bit. Not alot but its still there. I think that NHRA allows 1cc variance for that where others do not allow...

Re: Max. Effort Dry Sump Oil Pan For S.B.C. Drag Race

Most if not all dry sump pans do not have a kick out but a oil recovery pouch on the one side is common as the crank scraper has to have a place in the pan to send the oil to so it can be sent back to the tank for have air removed much the same as a windage tray breaks up the air bubbles in the oil....

Re: Max. Effort Dry Sump Oil Pan For S.B.C. Drag Race

A 4 stage scavenge system is not always just in the oil pan. Most times there is 2-3 in the oil pan and a PU line in the engine valley area towards the rear of the block. As all the oil will be flowing to the back of the block you need to use vent tubes to stop oil drain back into the center of the ...

Re: CC ing chambers

How close to you match the chamber volume? Does it make for a smoother running engine. A builder who seems to know something claims he gets 70 cc chambers with .2 cc's of each other....Is this close practical or possible? Absolutely I have seen some shops that have done work on heads that just thin...

Re: Big Block Chevy Windage control-was this a waste of time?

That is a very decent price for what the kit comes with.
Seems like there is several different manufactures/suppliers now that are putting packages like this together as specials as well but nice to see some keep them listed all the time.
And the extra rod clearance is a bonus for stroker builds. =D>

Re: externally balanced 89 Chevy flywheel interchangeability

It was a pro comp flywheel that was supposed to be stock balance weight. Turns out is was not. It was drilled opposite to the bolt on weight and after calculating the missing weight by measuring the hole depths and size I figured roughly 248 Gr. Turns out it was 235 Gr.. the extra drilled area on th...

Re: LS oiling problem

Did you install a NEW oil pump?? I know that some guys will disassemble and check the clearances etc. in the original pump if its for them self but they use a steel bypass valve in a aluminum pump body. Like many imports they suffer a similar affect they start up and have pressure then it goes away ...

Re: Big Block Chevy Windage control-was this a waste of time?

IMG_0499.JPGI made some lifter valley vents for my Mark IV big block yesterday-good idea or not? Just wondering if I wasted an afternoon LOL. I added a 13/16 hole at the back of the valley for an oil drain and a few more holes at the front of the block... Anybody else do this? good results? A small...

Re: externally balanced 89 Chevy flywheel interchangeability

If the flywheel is for a 1 pc seal block it should be fine. None of them are perfect but they are all supposed to be within the factory tolerance which is fairly broad. By the way, the crank is only externally balanced in the rear. The front is still neutral balance like most other small blocks. Fl...

Re: Parts Catalog's

You don't have to join to buy the spec books from AERA. They sell them on their web site. They cover all years they just get updated every now and then but for the AERA guys they are all online unless they request hard copies of the spec manuals. As I mentioned guys that have large collections of th...
