It's the power valve. The carb is your whole problem. Run 71/81 jets with the rear power valve blocked off. timing at 38 total.......unhook your vacuum advance. If you have to turn the idle screws out more then a turn and a half then the idle circuit is to lean------a common problem with a...

Your right about the lift on the cam taking a little power away and i agree. A set of 1.6 rockers installed and track tested would be a cool test on any purple shaft due to most of them being on the conservative side as far as the lift goes. There are better high lift cams available for sure...

The post before this is my a real world combination with the .484 cam. If I where to fully port my heads and run a 2.02 set of valves what do you think it would be worth for horse power????? I would only need 60 more horse or so to be near the numbers of the posted engine combination. I think...

Just use the cam you have like you said ---- BUT make sure you have the lifters in the same bores that you took them out of. If you messed up the order then buy new lifters. When lifters break in to the cam they are ment to stay with the lobe they where broken in to. If you run them you run the...

You need new gears and what size gears are you gonna use???? The gears are the key to how a cam works in a combination. It's putting the cart before the horse by choosing a cam first. You want to go mid 12's so you have to get the cam right. I think crane series racing cams are nice. This...

The springs are a super stock spring and yes the car will sit higher on the right side. When a drag car takes off from the starting line,the first tire to leave the ground is the drivers side tire. This puts more weight on the right rear. The car has a stronger right rear spring with more leafs...

The heads flowed 260. If you double the cfm,the cylinder heads should be able to support 520 horse power. If you look at the torque,it's higher then then the horse. That is a great street engine.

It's all about using the correct heat range. If it's correct for the engine, it will have very little carbon build up and they will run for a long time with out any problems. I think the plug looks good. A little fat at idle, or if you run a choke, it's staying on a little to long after start up.

Well said fishy68......... I have worked on alot of transmissions, but still wonder myself, how they work after mods have been done to them. Things get complicated because your changing one thing that effects another. I still have not built a transmission all by myself ,but i am getting close to...

I understand that there are higher rpm governers available,but i have never needed one. You are correct about the governor though.BUT..... I always shift my (67 coronet) manually when raced,like i said ,but when i did let it shift in drive, at 6200 rpm's ,it was a modified transmission(ger)...

The governor ,from what i have under stood, does effect the shift point's. I will try to read up on what i remember but i am pretty sure that transmission line pressure controls your shift points under full throtle and the governor controls it too, but how is where i will not say at the moment...

To fishy 68 ____________ I have adjusted all my cars and have never had a problem getting them to shift at any rpm i wanted them too. I always shift manually when racing but any torque flight that i have had, could always be set to shift at any rpm under full throttle when in auto drive. I...

When you make the kick down rod longer by adjusting it, you are increasing the trans.(line pressure) and making the shift into the next gear hold to a higher rpm and also shift harder and sharper. This is for leaving it in drive, and wanting a little more performance out of your torque flight.

Make the trans rod longer and this will make it shift at a higher rpm. When shifting over 5000 rpm's ,it is best to start shifting it manually. This will make it kick down faster and under less throtle. So be careful.

The cam you have now is good for the gears you are running. A good cam would have .530 lift and a tighter center line like a 108 or 107.This is because your heads flow well at .500 lift. It's just hard to find a cam with so much lift and not loose cylinder pressure due to a very high duration...

9 1/2 dynamic converter = 3500 stall A 107 center line will be better for low end torque.

3000 stall \\\ dynamic converter

750 dp carb (mechanical secondary carb) >> The 4 corner idle is only on the 750 and 850 dp carbs.(4 screws) all other double pumpers have only primary idle screws(2 screws) A 750 dp is one of the best carbs ever made and works on everything, so in the future if you build a new motor it will...

Same lifter \\ If you look up lifters at summit racing,it's the same part # for both engines.

To anser your question about rpm's ,YES. It's all about VALVE SPRINGS. A good 360 will handle 6500 all day long If the the motor is a good motor it will be fine and by that i mean/////////////////////////// GOOD VALVE SPRINGS MENT FOR THE CAMS RPM RANGE. You only want to raise your shift point...

My point is you can use a stamped steel rocker with up to a .509 lift cam. Most .509 lift cammed crate motors come with heavy duty stamped steel rockers. BUT SINCE YOUR GOING TO A SOLID CAM ,YOU CAN'T USE A HYD. ROCKER ARM.

yes a plastic or wood spacer will keep your carb cooler ,and also keep the velocity of the air and gas charge moving at a faster speed while going into your motor,filling the cylinders with more air and gas. This gives you more torque and horse power for any motor.

There is somthing on your freinds motor that has been changed from stock. Thats not to big for any stock motor. The only thing you need to watch out for is the rocker arm hitting the valve guide boss(top of valve guides) what are you trying to do \\ Build it the same as a stock motor. The only...

Use it \\\\\\\\\ perfect for a 318ci motor. Get a four hole spacer for the intake \\\\ Make sure you have enogh hood clearance. Use a one inch spacer if you can but if not use a 3/4 or 1/2 inch. It will be smoother at idle and a better running motor over all.8)

That intake manifold is better for a 340\360 ci cylinder head due to the intake ports being larger in size then a standard 318 heads intake port. What do you have on your 318 for cylinder heads???

WHY are you going to a mechanical cam. Don't you have stock heads????

FISHY68 \\\\\\\\\\\\\\\\\:thumleft::thumleft::thumleft:

to fishy68. What i am saying is initial timing is not really a performance setting. YES it will give you all the things you said \\ better mpg \\cleaner plugs\\ smoother idlle.UNDER LIGHT THROTTLE ONLY. But i am a little confused by your statment that your motor will have spark knock with at...

Hey abodyjoe, Glad to here his car runs great. I run my stock distributers with the vacume advance off and then turn up the total timing to 34 or higher. The distributer can be recurved if the motor wants it due to how it's built and going to be used.( a msd distributer comes with all the...
