Nice. Wondering how high you spun it and did the power linger or drop and at what rpm

What kind of car is this going in? I can't wait to see track times especially from an East coast track. It is going in a 65 Coronet

What we do is use a cam with smooth lobes, stay around .615 lift, hollow stem intake valves, Ferrea beehive or LS double spring and Ti retainer. We also use the Johnson lifter and either 20 or 30wt. oil...no more than 30wt. Also use Manton shafts to keep the rocker motion more stable.

What spring are you running? Me and Craig had a long conversation about this a couple weeks ago

What spring are you running? Me and Craig had a long conversation about this a couple weeks ago Using the manley 221439 springs. I will say the cam has a fast lobe. I wanted to use the hollow stem valves from the beginning but was convinced to keep the solid stems in the heads, still might put them in. My big concern is the lifter pump up with .060 P/V on the intake side. The exhaust is good over .100. How tight have you guys run these things? It did have 15w40 in it and it did have 100+psi of oil pressure, another concern I was planning to switch to 10w30 or lighter. Has anyone used the crower or isky lifters yet? Are the johnsons worth $750? Just steep for a hyd lifter I think.

Nice car. Crowers are Johnson lifters. I dont know of $750 Johnsons. I plan to run the axle oiled Johnsons in my next motor. They cost about 350.
That spring specs are weaker than PSI1515 that I use. Also, the best part about running Thiteks is using a dual spring.

Yep, dual springs, johnson lifter, and either go with a slower lobe, or lighter int. valve...you could even go Ti but you'll need to watch your P/V clearance as the margin on the Ti valves is much thicker.

The short travel Johnson's were quoted at $740. maybe I should look around. I would like to talk to Craig about what spring setup works best but I can't find any contact information anywhere. I really don't get the short travel lifter thing. Just measure for pushrod lenght and get a pushrod .020-.030 longer. Or less. Not sure of the growth amount on these g3 but i assume its around .005 If you have fb you can get Craig on messenger. I have his phone number but it might be his personal number I really don't want to give out
