Re: Fuel pump questions (big block street car)

I could always leave my electric pump in place with some plugs in it. It is on the frame right there by where the mechanical pump mounts to the engine. Big red flag, here. Electric pumps are good 'pushers' but not so good at 'pulling'. Mount in back by the tank...preferably behind and lower than th...

Re: Milling a -206 BBC head?

Can an OLD, -206, BBC head be milled down around 90 cc's or so OK? (97 or so cc chambers here). I think it is a way early 396 true closed chamber head with 2.07"/1.72" valves. I want to use them on a stock, mid 70's, 454 PU engine to raise it's really low CR up so that I can install a decent cam in...

Re: Fuel pump questions (big block street car)

A really good fuel pump for you would be this one. You can bypass the fuel at the pump right back to the tank so the fuel pump runs cooler. It's not super quiet but if you mount it with some rubber vibration mounts it would be reasonable for a street car. https://www.holley.com/products/fuel_systems...

Smokey used a strobe light when taking pix of the oil pan with the engine running. Timing chain, too.
David Reher has talked about dynoing a wet sump engine with no oil pan.

Big power. 8) Big mess. :lol:

Re: Too much oil in sump

Continued oil pan/oil system/oil level dyno testing on this 327 NHRA Stocker engine was worthwhile. :wink:

Re: Too much oil in sump

We've spent a lot of dyno time testing this on our NHRA Stock and Super Stock stuff. Each is unique as to its specific oil pan configuration but similar trends are seen.
The further you keep the oil level in the sump from the rotating assy, the more power you make.

Re: NHRA STOCK valve job

The OP is asking if it is legal in NHRA Stock Eliminator to use other than factory valves seat angles. I think he understands not every valve job works on every head and what it takes to test them. He just wants to know if his reading of the rule book is what is legal. And that is can you use other...

Re: Popping sound from valvetrain

I would be very suspicious of the valve lock and/or the fit between the lock and retainer. I've seen this a couple of times and it's been the valve locks that were dinged up. Be really careful, here.

Re: energy suspension motor mounts

I do have to jump on the engine and twist it all up to get the engune mounts onto the frame mounts and ining up the 2 big bolts is very difficult. art Assuming you have the correct motor mounts, leave the bolts loose between the mounts and the block and let it settle in. Then tighten everything up....

How is the bypassed oil being handled?
That depends on the pump. Some pumps will dump the bypassed oil back to pan, others will redirect it back to the inlet....
Yeah...I know. :wink:

I don't see where the O.P. has discussed it, other than to state what pump is on it.
