Re: EMC 289

Nice build and congrats!! =D>

Would make a nice engine in our XR GT FALCONS down under!

Interesting on the hydraulic roller cam with solid lifters...........how reliable would it be in a street car?

Would you add more exhaust duration if you made a cam change?......if so how much more?

Re: engine masters live feed?

Thanks, Walter. Good thing I wasn't handicapping this like a horse race; I'd lost big bucks. Who'da thunk a Ford FE would win it and Kaase's BBC would be behind the FE and a SBF? And there's a BBF 385 scoring lower than a Y-block and two FEs. And what's with not a single BBM or SBM competing? No Ol...

Re: engine masters live feed?

What was the issue with Kaase's engine? There were no issues that anyone could see ... simply not a high enough score. It said on the hotrod site he was down 60-70hp down from pre contest testing.........just curious if something went a miss. I like those Jesel rockers he had on the BBC.......also ...

What if you saw the worst valve train deflection ever and a loss of net valve lift how would you treat the situation?

Re: 904 (903) Mech lifters and various wheel size

You need to check, to see what size roller follower, those profiles were designed for. If they're designed for a .750" diameter, and you put a .820" roller on it, the acceleration rate(off the seat, and back on the seat) will be increased. This could cause increased pushrod flex and/or premature se...

Crane 96870 springs, set up at 165lb on the seat.
Cheers Tony

One would think that a .903 lifter would be the ticket here with a little more cam and be at 620+hp......and be a reliable street car!!

Do they make a .903 lifter for holdens?
