mossy74 Posted October 3, 2008 Share Posted October 3, 2008 I was wondering what options there are for the JTR kit so i can keep the stock latch, I've seen there are magnetic type which seem to be a lot smaller, anyone used something similar?

Yes, the smaller base diameter distributors should give you about an inch or so of room, I would think. Clearly, that would be the way to go, or you can go LT1 which has the Optispark located at the front of the motor. I have both distributors and I'll end up using the smaller base disty (Mallory) instead of the HEI. I don't have the motor in the car, so I cannot tell you if the Mallory has enough room in the JTR position. It would be nice to keep the stock latch stock Davy Quote Link to comment Share on other sites More sharing options...

With the stock latch still in place I could see no way to to do any engine work without pulling it back out. The stock latch keeps you from removing the distributor cap.

Administrators RTz Posted October 4, 2008 Administrators Share Posted October 4, 2008 If you're willing to go as far as aftermarket EFI, DIS becomes viable. Quote Link to comment Share on other sites More sharing options...

With the stock latch still in place I could see no way to to do any engine work without pulling it back out. The stock latch keeps you from removing the distributor cap. That's good to know. I'll probably go the hood pin route with my fiberglass hood (not installed). Eh, I have to still make up my mind anyway. Options, options...

mossy74 Posted October 6, 2008 Author Share Posted October 6, 2008 Definetly going carb, want to stay away from EFI, the smaller MSD looks interesting, i might mount the motor in place first then do some measurements. That MSD dizzy says it won't accept a vacuum canister, isn't that needed? Quote Link to comment Share on other sites More sharing options...
mossy74 Posted October 7, 2008 Author Share Posted October 7, 2008 This looks like it might work. http://www.msdignition.com/product.aspx?id=5593 Quote Link to comment Share on other sites More sharing options...
Guest Ilovetacos Posted October 11, 2008 Share Posted October 11, 2008 i am running a Big HEI but i am doing a trick firewall notch and running my hood on pins. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 11, 2008 Share Posted October 11, 2008 This looks like it might work. Hmmm, looks like you just need to know the height of the disty from the top of manifold vs the distance to the latch where it really starts to protrude. I thought that someone, someplace did this. It was a few years ago, so I can't recall. It may work. Davy Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 11, 2008 Share Posted October 11, 2008 i am running a Big HEI but i am doing a trick firewall notch and running my hood on pins. The firewall doesn't need to be notched when using an HEI in the JTR position. Curious, how is your engine placed? Are you using a kit?

SpeedRacer Posted October 11, 2008 Share Posted October 11, 2008 DavyZ - I did for one http://forums.hybridz.org/showthread.php?t=137949&highlight=distributor "Funny, I use this http://www.msdignition.com/product.aspx?id=5709 distributor because of my Tri-Power intake and MSD says it is "CNC machined billet aluminum housing is 3/8†smaller in diameter and 7/8†shorter than conventional Chevy V-8 distributors with the “points†type cap" but they never state the actual size." "I just went out in the garage and measured my MSD 8570 and its about 6 1/4" high off the manifold and the cap is about 3 1/4" in diameter. Sorry, its hard to get it exact." BTW the 6 1/4" high is to the top of the center boot and the cap is about 1 1/2" out from the firewall. I can't move the engine any farther back because the 90 degree elbows that go through the firewall for the heater hoses will hit the valve cover. As you can see I don't have a hood latch but it looks like the distributor would easily fit under one because it's 4 1/4" from the bottom of the hood opening sheetmetal (the lip with the weatherstrip on it) to the top of the dizzy. Hmmmm... I think I need to clean my rear carb and dust off the dizzy. Quote Link to comment Share on other sites More sharing options...
DavyZ Posted October 11, 2008 Share Posted October 11, 2008 Wow, it's amazing what the search function will yield. Thanks for posting that Speedracer. I think my memory is worse than I thought--the thread was from August! Davy Quote Link to comment Share on other sites More sharing options...
mossy74 Posted October 11, 2008 Author Share Posted October 11, 2008 Here is a pic of my latch, looks like it might fit, I guess cost is a factor also as a small diameter MSD dizzy with 6AL will cost about $900 AUD and an MSD HEI will be about $200. From my JTR book it says with a HEI the tacho needs to be replaced with a 260z model, is this the case with your dizzy speedracer? One more option I've been thinking of is modifying the stock hood latch, maybe cutting off the whole bottom section of the support leaving just the top then welding two support arms to the firewall on a wide angle?
