Re: BBC connecting rods

Hardly worth spending money on old rods that might be out of balance, out of round, old fasteners...considering the cheap cost of new rods made from better steel.

Re: Timing gear misalignment

First I would be finding out WHAT is causing the 0.030" discrepancy.

Re: Steel Main cap material

Steel & cast iron have virtually the same expansion rate, relative #s are 11.5 v 12. Only when you get to stainless steel do you get a major change, about 16.

Re: Ford TFI coils...

Why don't you contact MSD & see what coil they recommend? If the Blue Streak is a canister coil, I'll bet they won't recommend it for optimum spark performance.

Re: Oil pressure vs volume

Yes, large lift variation between rockers. Very good chart in D.Vizard's BBC book, where he tested different rockers with interesting results.

Re: Fuel pump questions (big block street car)

The Carter electric pumps are more reliable, probably the most reliable of the elec pumps for external use [ not in-tank ] for carbs. They have fuel circulating through the elec motor section to cool the pump & lube the brgs. There is NO internal seal a la Holley to fail. The Holley on my mate's car...

Re: Need to run EDM solid lifters?

I have been grooving lifters for 30+ years. Use a Dremel with a 1" cutting wheel, 0.020-0.025" wide & grind the groove. Start at the oil band & go to withing 1/8" of the lifter base, not critical. Use 180 emery on the groove to smooth any high spots.

Re: Tachometer vs HEI Limiter

Most of the HEI modules I have seen with adjustable rev limiters that use a screwdriver slot for adjustment are a potentiometer - a variable resistor. Most use a cheap carbon track as the resistance medium & it can change their value [ ohms ] with age & heat. Hence setting the rpm at a particular se...

Yup, cam timing. Assuming ign timing marks are correct.

Re: Modification advice for 331 Ford

Crane cams claimed that when advancing or retarding a cam, it should be a minimum of 4* if you want the butt meter to feel the difference.
Advancing the cam will also reduce intake P to V clearance, should be checked.

Re: Carb too small?

Maybe a distribution problem. Try changing the position of the sec blades at WOT. Easy to do with AFB/AVS carbs.

Re: Applying the DV 128 formula on a Supercharged engine

SMW, You are indeed trying to 'sell' something in this thread & on others from time to time. Your 'sell' is that DV is a fraud, is not a professional & the 128 rule is a fake. Enough of your glib one liners. Time to put or shut up: create an engine with some specs & give us the cam details using YOU...

Re: Applying the DV 128 formula on a Supercharged engine

SMW, In your haste to denigrate DV at every turn, you forgot, or never knew, that 128 was an approximation for the hotrodder. It is a starting point number that covers some engines & some compression ratios. It saves the hotrodder from the phone jockey at Comp, Crane, XYZ from recommending a cam fro...
