Looking for a good HEI Distributor and coil (prefrably one that mounts on top of the distributor) for a basically stock LG4 305. All emissions have been deleted except the fuel evap cannister and EGR..those are staying for now. Considering a remanufactured Q-jet for carburation (don't like the Edlebrock/carter/weber carbs). Prefer something that will operate reliably for daily use but will also respond well to mild power upgrades (exhaust, headers, Intake manifold and possibly cam and timing chain set later on).

Also considering doing Intake manifold at the same time since I have the carb and distributor off the car...as far as intake is concerned, I'm torn between the Edlebrock Performer and the Weiland Action Plus. the Weiland I think will do me better with more performance upgrades...

Also doing a 160 degree thermostat with the Carb and Distributor.

Any suggestions? Ideas?

Since it sounds like you have some problems working on carbs Wink

the 600 Edelbrock would work great on your mild combo. They are simple and realy easy to adjust and tune. Why don't you like them? I had one on my car for quite a while until it became a restriction.

You could get a junkyard HEI distributor and put a new cap and rotor and prolly be good to go. You shouldn't need to spend tons of $'s there right now.

Just don't get a parts store reman q-jet. That is unless you like to change carbs over and over till you get a good one. Nothing wrong with a good q-jet though. It will get you good reliable power and decent mileage. Throttle response seems to come in somewhere between a holley and the edlebrock.

Was just thinking. Is the LG4 intake you have now aluminum? If so it's pretty much equivalent to a performer allready. Some say its even better then the edlebrock. Might be a place to save money.

Brandon,
My manifold looks to be aluminum...I'll see if I can take some de-greaser/carb cleaner over it and find a casting number. I have 3 Q-jets, Two are missing there base plates and have two attaching screws on the bottom that attach the base plate to the main body, and two long ones that go through the top. The CC Q-jet off the LG4 is the only one with a base plate, but it has four attaching screws on the base plate and two through the top. Other than than, it'd fit perfectly on the other two. Shrug

I'll probably rebuild the Q-jet myself. If not I know a guy who has always done a good job on rebuilds in the past...only charges about $100 to rebuild and that includes parts.

Hammer,
Its not that I don't like the design of the Edlebrock/carter, Its a fairly reliable and easy design to work on..HOWEVER.. I've worked on 3 different cars that have had them installed, and they all would want to run full rich and any attempts to lean them out would cause severe shuttering or stalling, even with clean spark plugs. Checked the vaccum at idle from both the distributor and carb and seemed to read exactly as it was spesified in the shop manuals (one was a Dodge the other two were Chevy's) ...I think its probably like the parts store Reman Q-jets Brandon talked about, and these ones were just bad. Its just made me a little apprehensive about putting one on my car. I've also heard other horror stories about other Edlebrock parts...except the intake manifolds..I figure with a manifold they can't possibly screw that up, since it has no moving parts. Wink

My edlebrock carb was actaully way lean. Had lean surge all the time till i richened it out a step and half. Everybody else says they're always rich. Main thing to look at when rebuilding a q-jet.. look at how much play is in the throttle shaft. If its worn too much it won't run right at all. I bought a reamer/bushing kit to rebuild these. I think i still have enough for another carb. You coming to cows? If so it might be possible to rebush the baseplate while you're here. Most rebuild companies don't do this.

great tech article on TGO about taking your carbed engine to non computer controlled. i read up until it said "advanced setup" and then i realised i was filling my heaad with shizzle i will never need to know.

Pertronix Flamethrower HEI Rebuild Kit ... I was most happy with it... its a new coil/cap/rotor/module/springs and, this is possibly just me, better than the MSD (well, at the time, pricing of course was a bit different then too)

I'll keep the Hypertech in mind paul..

My next question was going to be if I can reuse the stock Coil/Cap since they're in good shape.

Went with Tony to a couple different junkyards. Couldn't find a baseplate that fit...either the bottom screws were different or It didn't have fuel mixture screws, Saw one that might have worked at Damascus U-pull but it'd been in an engine fire, and I didn't feel good about taking that one. They did have an Edlebrock carb there for $45 with an Electric choke. Thinking about going back and snagging that one. Not sure I can really afford it now though.
