Re: Weld or putty

Another vote for pin* no risk there from the heat of a seat falling out or guide repair needed. Just a good mechanical repair that shouldn't give anymore trouble. Welding would be the best fix, but sometimes what's best and what's the most practical aren't the same.

Re: when are 3/4 grooved main bearings needed for bbc ?

I have been trying for some time now to set my oil timing...can someone explain that? Do I need a dial back timing light or will a standard one work?

1575 valvesprings

Are PAC 1575's and PSI 1575's the same spring? Just a reboxing type deal or are to spring manufacturer's making 2 very similar springs?

Re: Opinions of guides in import heads

Yes, if you want to check for roundness, taper and clearance the correct way. If your checking to see if they are worn out you can do that with the heads on the motor, but you need tools to be able to take the spring off on the motor.

This is a good question...did you build it? Not putting you down more or less asking if you know for sure it is 427 ci?

Re: Help for tips 427 csb

What does this car weigh and what elevation are you racing at? It seems to me you must be having traction issues because your 60ft times are pretty slow. I would think even a pump gas 427 should run 6's in the 1/8th with AFR 227's on it. What is your ignition set up and the timing initial and total?

Re: Race Engine Challenge intake critique

Carnut, Do you think the burr finish on the outside of the intake was worth any HP on the Dyno?...lol. It's a great looking intake by the way. Nice job. Myself, as a hobbyist have a decent handle on porting heads, I'm talking about what tools to use burrs, stones, sand rolls and how to use them to g...

Re: Wanted, used parts for homebrew engine "cocktail"

I see in the thread for this that you are thinking of mix matching rods. I have a complete set of 8 scat I beam rods, they are the ones that look like a stock rod with bolt and nut. Only thing is that one rod needs a bushing in the small end. All are 5.400 with a sbc journal and Chevy pin. I would d...

Re: Camshaft grinding wheel supplier?

Good luck, and let me know what you find out. We keep 3 different wheels mounted on hubs, and all 3 are custom compositions. We have one for roughing full circle steel billet cams prior to heat treat. We have one for finish grinding cast iron cams, that we just switched to last year. We have one fo...

Re: Finally figured out how to move some air on these heads...

Are those heads anything like E7's? The 1.84 valves worked out pretty well in a set of those I ported. I lowered the Apex of the intake SSR around .080" and smoothed out the radius from there. That was worth over 10cfm. I ended up with those heads going 214 at .600" lift. Not monster numbers, but ma...

Re: Sbf oil pump for 8000 rpm

Lots of wide clearances everywhere....... I know your involved with Nascar, but I would bet none of your engines have a 3" main journal like his. I agree that the rod clearance is a little loose though. cgarb. The OP has not stated what size or configuration his engine is. If it was based on a fact...
