Re: duration @ .050"/ .200"

Not sure lift has to be more if the .200” is greater

Plenty of cheater cams have bigger .200” numbers with less lift than those with smaller .200” specs and more lift

Re: Top piston ring gap - whats really required?

In a perfect world where cooling systems keep every cylinder an identical temp or never ever spike in temp from a problem , you can probably take a chance on closing the gaps up... if you have the slightest issue, you could be in big trouble It may even be possible to measure the increase in power a...

Re: Mail in voting

I would prefer taking a chance with the post office over that drop box. I like the way in person voting works here. My identity is confirmed. I fill out the ballot. The ballot is handed to a judge who asks you if this is your signature. He/she then puts it into a machine while I watch. It reads the...

Re: SBC LT1 / vortec compatability

Cloyes has a factory roller cam specificd double true roller 9 key way setup. It fits all timing covers with lots of clearance including the plastic covers. Makes a nice change from the sloppy sets as they can be had in -.005 and -.010 shorter lengths. =D> =D> No block grinding required. I have use...

Re: SBC LT1 / vortec compatability

Any timing gear made for the stepped-nose cams, either 87-93 Gen1 or LT1/LT4, should have clearance for the cam retainer plate and bolts, as the stepped-nose cams were never used without the retainer plate. Changing to a different style bolt with a fatter head can cause clearance issues. Some after...

Re: Stock Eliminator secrets?

Easy enough to correlate to those conditions if you don’t want to haul it there With a Physics background, I can likely extrapolate without need to sharpen a pencil nor dust off an abacus. :wink: Back to our regularly scheduled program. Here's a NHRA accepted (stock depth) oil pan for a Stocker. Lo...

Re: Stock Eliminator secrets?

Happy to. The car is a '68 Chevy II, 327-275 h.p. that runs in G/SA class. The NHRA index for G/SA is 12.00. If the track is above 1,500 ft, the index is adjusted from that. This is at Pierre, S.D. this season. Index there is 12.15. The car went 11.155 (-.995 under the index). The 11.14 on the side...

Wasn't you that came to CutlasEFI"s defense regarding some ridiculous TQ to CU IN claims he was making with his inaccurate dyno testing over on the REAL OLDS forum? Not me...I may have said my 307 olds for the EMC made 1.44 TQ per cube back then, I have no idea what engine he was talking about. In ...

Re: Stock Eliminator secrets?

Thanks for the info..looks like your knocking on the national record...10.8 correct ? If an NHRA National Record has not been set in a class for two years, it reverts back to what's called the 'Minimum' , which is .50 under the class Index. At this point in time, the G/SA National Record is at Mini...

Re: Stock Eliminator secrets?

The takeaway from this is.....you have to run what is accepted, per the NHRA. You accept that as part of the deal when you race in Stock Eliminator class. It's also a big part of what you look at when researching a possible build. What's available? What's accepted? What's the potential? What are th...
