Re: distributor. final ignition time

YES, there is a formula for just about every motor situation, but you need to know when the intake valve closes for accurate dynamic compression, static compression, rod length, deck height, volume of any dish/eyebrow cuts in pistons and head gasket piston diameter, plus the crush-height of the head...

HEI ignition

I am installing a GM style HEI on my modified 200 in a 65 Mustang. The car is built ground-up for interstate highway running, not MAX HP. It looks like running a hot wire direct from the battery to a relay, then to the dizzy is the best setup for max spark. The plugs will be opened up to .045" ...

Re: Rough running above idle?

If pulling the choke speeds up the motor, you are not getting enough fuel. The choke shuts off AIR, so speeding up means you are matching the air flow to the fuel flow. Look for a problem with fuel delivery like clogged jets, low fuel in the bowl, clogged filter, etc.!

Re: oil capacity questions 66' 200 6cyl

I am a retired engine builder (mostly stock/near-stock) to go in Street Rods for long distance running. I have rebuilt a 200 Six twice and both had this overfill problem. After running about 20 miles I checked again, and the overfill was still there. The blocks were hot-tanked, the head cleaned and ...

Re: Yet another static compression ratio question

DO NOT FORGET, the octane of regular gas when the 170 was new was 92! My 65 Mustang came with 9.2-1 compression and like most old V8 Hot Rodders, I bumped compression up too much and busted #6 compression ring. That caused a .060 overbore which is not normally recommended for the 200 six. My Static ...

Re: Rookie Dual Advance Vacuum Question...

If any 200 six is changed to a Dual-Advance (swing-weights and vacuum) from a Load-o-matic (vacuum only), then MANIFOLD vacuum is used to the advance side of the vacuum chamber on the distributor. I highly recommend a SINGLE vacuum distributor because the vacuum chamber with 2 connections is for emi...

Re: Headers (200 six)

Not to rain on anybody's parade, but the 3/4 exhaust port divider seems to be a waste of time. Dyno showed no change but some came undone after a short time of use and rattled! I seriously wanted to do this for my rebuild last summer because "on paper" it seems a good idea, but research sh...

Re: Is an Autolite 2100 worth it on a stock 200ci?

Thanks for all the "tech" info about the 2100 on a 200 head. I have built engines for over 4 decades but not this engine...until recently. Two rebuilds have shown me ethanol gas and too much advance can kill number 6 compression ring. After a .060" bore, installing a 1968 dual-advance...

Re: Battery ground location, '65 200

You can't have too good or too many grounding places! I use "star" washers under my ground connections and go with heavier copper wire than OEM. My degree is in electronics and I spent over 40 years building cars from the frame up. My ASE certification is in engine building and I have see ...

Re: two barrel adaptor

With the stock carb a spacer with water passage is used which also properly positions the carb square with the head. If that spacer is eliminated the carb sits cock-eyed...which is okay but looks strange. Also, in Texas heat is a problem so the aluminum spacer helps keep heat out of the carb. I have...

Re: two barrel adaptor

Thanks guys. My concern is hood clearance and linkage. As a long time street rodder I am sure I can make it work, but I will never get too old to ask. I want to avoid any computer/electronics so TBI is basically out...for now. In the future I may give it a try but right now I want 25mpg, about 140 h...

two barrel adaptor

Has anyone used the 2 to 1 adaptor from Summit? I am happy with my 1100 but as the 1st gen. GURU for the Mustang 6 Association I want to try adapting a 2bbl using over-the-counter parts for an article. I have a 2100 (108 version) which is 287 cfm. With a .060" overbore, minor head work, hotter ...

Re: more performance and great MPG.

The big six is not an economy engine but a brute strength-long life one. However, if built for torque with the right gears and tires it can become a good MPG hauler. I had a stock 3 speed years ago I used as a parts chaser while building street rods. Do NOT over carb it! That is the biggest mistake ...

Re: Heat shield

Heat shields are available from coolcarb on line. I use 2...one under the carb and one under the spacer, plus I reroute the water line to the heater away from the carb completely. Now air goes there. Wrapping the exhaust with "heat-wrap" should help. As for cleaning the intake, use a drill...
