Had the PR length set but then I changed rockers & found I now have .05 sweep I & E before it was .03 I & .025 E. I think the difference is the diameter of the roller tip the new rockers has a roller dia. of .6 & the others .475. The "difference" you are observing probably...

I'm looking for some feedback on a set of shaft rockers to fit the Ford Racing Z304D heads. Jesel is closed until Wednesday due to the impending storm. Anyone else make a shaft set-up that fits those particular heads? Really in a panic, need a set of good rockers to go on a customer's aluminum bloc...

I've tried many different lengths of pushrods but still can't get the sweep pattern on the valve tip below .085 on the exhaust. Intake is over .100. This is a stud setup on a BBF. I also tried three different 1.73 ratio rockers. That didn't help. The Comps made it worse and moved the pattern away f...

I used to race a 100cc Yamaha KT100 engine set up with a squish clearance that measured a ridiculous 0.015" cold (solder measurement). At 13,000+ rpm down the long straights, the EGT would rise steeply and I could then hear the piston start lightly kissing the head at TDC. At that point I'd jus...

the clevite set is a full groove bearing. I was more concerned about the construction of the bearing thanks donovan Which bearing construction you opt for (steel, babbit or V-style) depends on the build details and engine application, and, to some extent personal choice. The full-groove Clevite 103...

Okay FE gurus. I'm sure you've seen these cracks before...Both heads have cracks that run between the intake valve seat to the spark plug hole. The heads need intake seats. My question is, will these cracks end up hitting the water jacket? These heads are not as easy to find as they were, so if I c...

I have a bbf engine build that I bought a after market crank for, the main and rod journals are big so I needed some x bearings this is what clevite has ms-1039mx which is a steel back babbit bearing. my question is will they be ok for a street strip build. thanks donovan Short of a bone stock (non...

X2. If the waterpump's anti-cavitation backing plate was left out then the 385 Series can experience the overheating symptoms being described.

I am rebuilding a '74 460 for a friend of mine and was wondering at what size camshaft does one have to convert the pedestal mount rocker system to an adjustable type?? 9.5 compression, balanced, and a little head work w/ 2.19/1.75 valves. The cam he wants to run is a hyd flat 234/234 @.050" w...

How close are the designs of both of these heads? Both have same port volumes and valve sizes for the standard port location. Are there any major/minor design changes in the Trickflow head over the SCJ? I've worked on SCJ heads before but not the Trickflow version. The TFS Street Strip and the SCJ ...

I am working on a head casting design to fit a common 460 block. I just went to pick up a head gasket to make sure it fits up. The gasket looks like this one with two holes on the intake side that don't match anything on any of the blocks or heads I have been looking at. Does anyone know what these...

Peak HP & TQ?

Peak RPM?

Steel or aluminum rods?

Power adders or NA?

Fuel type?

1st off it's genius, not genious ... If you are going to degrade my intelligence at least get it right in the spelling department... Thanks, I know how to spell. That oversight isn't from a lack of ability to spell, it is simply not proof reading what I type. :lol: 2nd I hope that anybody that read...

F1Fever, I stated that I would no longer reply to your posts, but you seem to be constanty re-iterating the same thing over and over....as though you are walking the room trying to pick a fight. Specifically, you keep posting the following pics... [img]http.jpg[/img][img]http:.jpg[/img] I also know ...

What's the best OEM block to start with for making a healthy N/A street engine? We were talking about building a big block with fairly modest pieces. Heads that take standard kind of valve gear (keeping rockers in the $500-700 range), OE block, probably OE crank or budget aftermarket piece, economy...
