So this is where things really do get interesting, here is why. There were no bent pushrods, no wiped lobes. Because of the design of the retaining clip it was "captured" around the pushrod, so neither it nor the lifter cup itself ever escaped into the motor. This was a great outcome, no damage...

Hmm...interesting take on the situation, because your message certainly reads like I basically haven't followed any of the proper engine assembly processes...which happens NOT to be the case here. Springs were matched up to the cam. They were checked, valve close & open pressures were verified...

Is this what your lifter looks like? These are the SpeedPro Anti Pump-up lifters...well, originally this is what my machinist picked for me and what I used in my 360 motor. I (as per the mfg instructions) had set them up for 0" (zero) preload...they worked great, but eventually I found out...

Cool stuff...very similar to what I crafted and that was based on a mag article...not sure which Mopar mag though. Here is what mine turned out like:

Reading the instruction sheet (attached for reference, sorry, not the best quality though) that came with my W2 econo heads I find the following: "...It uses a rocker shaft that has the attaching holes on-center. The T/A shaft P3577086 is recommended..." So I am guessing we are talking...

What are you talking about??? Seriously, the OP asked a simple question: "..for an iron headed small block at about 9.5:1 compression...what is the least amount of duration you can get away with before you have detonation issues..." So my response, as clearly stated, gave him feedback on what...

I am (almost)...Hughes HE3844AL hudraulic flat tappet...238/244 @ 0.050"....verified 9.7:1 static CR...fast ignition curve (21 initial, 38 total)...no detonation on 94 octane, dynamic compression is 165-170 psi. In fact, I just picked up my heads from the machine shop as I'm going to a 10.5:1...

Valvoline VR-1 10w30 here...with my high-volume oil pump I get 50 psi cold pressure and 25-30 psi @ idle when HOT (900-1000 RPM) with the preferred 10 psi/1K rpm climb in pressure afterwards... My main bearing clearances were: 0.0035 and rod bearings were: 0.0018 with 0.012 side to side clearance.

I ground the covers...but since all I had to do was to make elongated U-shaped cut-outs and that was just to the outside lip it actually fit really well with the intake...make a nice job of it and you won't even notice!

I do not own a MSD box, but it's a multi-spark in the lower RPM right? So is the root cause here the fact that the timing light is driven by the spark signal in the wire and most likely either catches the first or the last MSD pulse?

To clarify, my comment was not a recommendation regarding how much porting the OP do, it was merely an illustration of the potential of 596 castings if one were to CHOSE to port for max flow gain. Now, consider that these flow numbers are for a 180 cc intake runner...that's stil a pretty good...

Thanks rumblefish360...yeah, I found porting heads to be one of the more rewarding undertakings...but you are certainly right on the money with the time estimate...it probably took me a good 60 hrs/head and this is already having some experience with using various bits, shaping ports, etc...

Here are some DIY porting results on a set of 596 castings. This was about a 3rd set of heads I ported, pleased with the results. Your are probably not going to go that extreme in terns of the port work though. LIFT I E 0.100 67 57 0.150 99 79 0.200 130 104 0.250 162 125 0.300...

Ahhh sir...you have come to the right place!!! Been doing work with TQs for years now...I have an 9800 series in my coupe as well. I've attached the setup instructions for the matching Carter carb kit, this should get you started. Post some more info regarding your combo and what you're...

Head is the factory iron '596 casting, having gone through a DIY porting effort but with a 3 angle valve job by a competent machine shop. Here are the flow numbers (flowed on SF-600 @ 28" water): LIFT I E 0.100 67 57 0.150 99 79 0.200 130 104 0.250 162 125 0.300...
