Don Terrill’s Speed-Talk

Im just shocked that those heads were assembled with painted springs.. probably broken valve spring caused some carnage.. if you can get a deal on the engine, go for it. Anything can be fixed. Its pretty expensive to build a 12 degree deal new these days. So even after its fixed you'll be ahead. MT...

Hence my tongue and cheek joke about Straub..........Your shop builds some impressive engines from the posts you make on yellow bullet.

All good i was only joking, are you the same guy on yellowbullet with a straub quote in your sig.

Get Straub to do a custom cam for you.......

No, ellipsoidal is dual taper and not a tree shape(tapered)

Warp has always said straight tubes is the best option.

So you would think next best if straight don't fit would be single taper followed by dual taper pushrod in the same diameter.

Come to find out I didn't need all the build up on the outside (front and rear) of the plenum and made a small mess roughing it out this evening. if this bit were a tractor it would be a D11-R. This things moves some material like NOW .... https://hosting.photobucket.com/images/aa150/Sleepercp/IMG_...

Walter, like i said i could be wrong.....i found them max pressure's from ISKY cam's website all there Johnson lifters are rated 185/530 pressure's. I just don't see why someone would need so much seat pressure with a small, low lift 55mm hydraulic cam. MT i was referring to Walter's build with .74...

I know, but the spring pressure's are rated @185 seat and 530 open pressure for this lifter, i could be wrong... #-o Where did you get those numbers ...? Certainly not from Specialty Engine Components; those who manufacture those lifters. Walter, like i said i could be wrong.....i found them max pr...

Johnson ST2126

ST=short travel

I'm the seeing the answer is in all of the above. A guy like Steve, who's constantly experimenting on the flow bench, is seeing an advantage (or not) when moving the rocker ratio around. That's with a given cam and an unspecified cylinder head, Unspecified in that it's constantly evolving. The rati...

I have mast small bore LS3 heads for my LSX, and the stainless intake valves I have for them are 126g (2.08"x 5/16“ x 5.45" length). I love these heads, but the long valves are HEAVY! How much spring pressure am I going to need, in order to control these valves at 8000rpm? Comp cams HLO S...

Gary Stinnett makes the same power with iron or aluminium..........go to 20:00 min mark.

Lake speed did an interview/talk with Kaase about EMC and how streetable one of them engine's are and Kaase just laughed :lol:, saying it would be a turd on the street, and that they would build it totally different for a street car. That would very much have to do with what the engine built was th...

All good!! Yes i'm from Geelong as well. Small world. Something gave me the impression you were in qld. Maybe you have seen this at local meets Yeah seen it years ago, haven't been to many car meets since covid began, alway's something comes up or shitty weather. The BP meets should be back next ye...
