Good info there, thanks for that rmchrgr. I've most definitely got a full 12V in crank and run. Main power goes right to the battery, and my switched pink wire is on a relay that has its own feed directly from the battery also. I didn't want to chance anything with the wiring and being...

Well, I got it all buttoned up tonight. I initially switched the ignition all back to stock and had issues getting power across the ballast resistor. Dunno why, but it would have power on the hot side for both pins, but only power on the opposite side on one pin. So coil wasn’t getting power in...

And that was my whole dilemma yesterday when going over all my checks before doing initial, was "if this MSD 5300 is a CDI box, and I've hooked up to coil -ive, I'm about to fry my Sniper". Holley had no idea about this box and it was hard to find anything online, and if I did find anything it...

Thanks for all the replies guys, it appears there's still much more for me to dive into this project than initially anticipated. I was under the impression these things setup fairly easily, but maybe there's more hiccups with a Mopar setup? @67Dart273 , that manual is the one I am using yes...

In the midst of hooking up a Sniper EFI and have ran into some questions about which method to hook up the ignition wiring to it. My main issue is with what kind of box my MSD 5300 is. Here’s my ignition setup: Ignition control Unit: MSD 5300 (like an orange box, has the stock Mopar plug)...

@RAMM specs in post #16. But for refresh this was the parts list: Pushrods: Comp Cams 2112 (7.500" x 0.080") Valve Springs: Crane 99835-16 Retainers: COM743-16 Valves: Ferrea FERF5003-1 & FERF5005-1 I also did double check the measurement I wrote down, and it was 1.562". Unfortunately I don't...

Thanks again everyone for the information and replies. I would definitely agree with Jesse, the fact I cannot get an accurate measurement doesn't help with correct findings on installed spring height. There's really no flat part on the inside of the head casting to take an accurate measurement...

I'll give it another double check tonight and look at some others. Just to be clear, that measurement didn't include the spring cap. Out of curiosity, if the springs are getting to the point they're close to binding, is the solution different springs, different valves or both? This engine...

back from the dead! In the process of getting a shop built, so the repair has hit the back burner. Took other valve cover off and inspected all the other rocker arms and nothing seemed abnormal. Measured height turned out being 1.562”. Which was from top of spring to bottom, on the valve that...

Never got the chance to get out to the garage to look at the situation any more. @RustyRatRod, ouch...with exchange and shipping and taxes that's close to $1200 for a set of rocker arms....I think at that point I'd swap out the springs to the ones recommended to go with the cam. @GEO, if only...

I'll be popping out to the garage this weekend, see what I can find and get some more info and checking all the other rockers. @nm9stheham, I'll take you up on that offer. Once I get out and get some measurements I'll post back here with what I find. At this point, there seems to be a lot of...

Summit Racing 'Applications' tab shows the following: Installed Height (in): 1.600 in. Seat Pressure at Installed Height (lbs): 113 lbs. Open Height (in): 1.150 in. Open Pressure (lbs): 280 lbs. I don't know if this is correct. I could always confirm with the manufacturer.

Thanks for all the replies guys, here's all the info I got from the builder with the engine. Here's the cam spec card: And here's the info for the other components in the head (provided by the builder): Pushrods: Comp Cams 2112 (7.500" x 0.080") Valve Springs: Crane 99835-16 Retainers...

Have a LA 360 with EQ magnum heads on it. It's always had a little miss, which I attributed to ignition and carb issues, so I did plugs, wires, distributor and rebuilt the carb (needed a good clean anyways). The miss never really went away fully, but it wasn't horrible so I figured it was just...

Thanks for all the information and pointers guys, it's very much appreciated! Have a lot to ponder about which route I want to go. I'm going to give M&H a shout and confirm with them exactly what their 69 harness setup for electronic ignition is. As much as it is more expensive, I did contact...
