Re: SAM's SB2 At The EMC And The REC

It gets old being challenged on everything a person says here on some issues, and completely dismissing the experience of some of us as being stupid, or liars. At 74 years old, with four college degrees, master instructor experience, and college teaching automotive classes, I only make a reply when ...

Re: LS 7deg Locks

When I did an installed height check with the 8mm retainer, and 5/16" radial locks, the locks sat down ~.120" in the retainer, and the valve stem was actually below the retainer, so a no go. Also, the 5/16" locks did not fit inside the 8mm retainer well enough to lock in place. You could open up the...

Re: LS 7deg Locks

I find the LS locks fit the 8mm stems, not the 5/16". That .002"or .003" makes a difference in clamping. Joe-71

Re: Modification advice for 331 Ford

At 331 cubic inches, you will be better off with the AFR 165 CNC Renegade heads on the street and occasional drag strip trip. The 185 heads will make more horsepower if you change camshafts and take advantage of the increase in flow above your current camshaft. A good beehive spring, titanium retain...

Re: The Venturi effect

On page 59 of your Theory Book you show a diagram of what at the time was considered an optimal venturi for a port and valve seat. For many years I tried to use that diagram to improve my port shape on almost all my work, and it did increase the airflow when testing on the flow bench. It works well ...

Have they wet your fingers for the finger prints? That usually helps. That is what they did when I had to get mine re-done for all five on both hands. It solved the problem. Joe-71

Re: Blasting media to restore as cast finish to alloy?

Black Diamond, or #3 sand at low pressures will give a porous finish to aluminum. Then steel abrade at low pressure for shiny, new look. Joe-71

Re: Checking springs adjust pushrods clearance vs the real thing.

Aluminum or steel rocker arms? Makes a difference. Harland sharp will tell you .020-.022" less with aluminum deflection on real spring. Joe-71

Re: Help with a land speed ls engine

I have to disagree with any rod length, when going for 5-7 miles at maximum rpm. There I would use the longest rod possible with big bore and stroke needed for cubic inches. That is a long time to keep the rpm at maximum without lifting. Joe-71

Re: Oil Smoke driving me crazy

If it was smoking before the build, then there may be a build-up of oil residue in the exhaust system that needs to be burned out. Drive the truck for several miles at a sustained speed after the rings are seated, and make sure the exhaust/mufflers are not contaminated. Seen this lots of time before...

Re: What SBF head is this? 289hipo/302/hi-port iron hybrid

The 289 had 2V heads, 4V heads, and 289 HP heads. 2V just had 289 cast, 4V had one dot above 289, and 289 HP had two dots cast above the 289. In the picture, you can see the two dots indicating true HP heads. Also all HP heads had the recessed spring pockets cast in. Joe-71

Re: Has racing been completely shut down?

Some of the local hospitals here in San Antonio, have whole floors that are shut down, and nurses sent home due to no patients. The order to stop all surgery except emergency has left many in the medical fields without work. You don't hear that side of the problem. Rules made by simple minded politi...

Re: Mushroom Flat Tappets/Tappet Weight

Not implying anything but that 292-312 Y Block Ford mushroom lifters are available from a variety of sources. The Y Block lifter bore is ~.500" stock, and there is usually a .002" clearance. They have a 1.000" foot. Race mushroom lifters are another category. I use the Trend tool steel lifters in th...

https://www.summitracing.com/search/part-type/lifters?fr=part-type&SortBy=BestKeywordMatch&SortOrder=Ascending&keyword=292%20Y%20Block%20lifters You have to call Trend, they make them out of tool steel. Hylift Johnsons are available if you just google them. Pioneer, Comp Cams, others have them, also.
