    Rockers

    The cam you are running has an intake lift of .496 and an exhaust lift of .520. Adding 1.7 rockers will get you .527 on the intake and .552 on the exhaust. I read somewhere that the max lift of 351 heads was around .500 but I couldn't be sure I would check that before committing to the 1.7...

    408w Windage Tray Question

    Obviously a windage tray prevents the crank counterweights from dipping into the oil and injecting air into it. Air in the oil is not a good thing. Oil level in the pan in relation to the crank might dictate the need of the tray. Most stroked engines would benefit from a windage tray...

    Squeezing out every pony

    The aftermarket intake and throttle body might help a little, but the fact that you have stock heads will prevent it from performing at its peak. With a good set of heads and cam it's a must. The best way to go is with a matched set like a Holley systemax which is an intake,heads and a cam...

    Squeezing out every pony

    The only thing left that I can see is maybe cobra 1.7 roller rockers . That will give you a little more valve lift and cut down on valve train friction. You could also try a trickflow intake with a 65mm throttle body and spacer.

    EFI to carb or keep EFI?

    I guess you can't argue with progress. Back in 72 when emissions control started to rear it's ugly head I thought that the hot rod was slowly dying , obviously I was wrong. The great thing about this country and the people in it is even with the government putting limits on auto emissions. We...

    EFI to carb or keep EFI?

    Just remember there were carbs before efi. Carbs have come a long way .A carb setup can pass emissions.I have had nothing but trouble with fuel injection. I am considering swaping out that efi pain in the ass. If its not surging its not idling right. Computer controlled cars drive me nuts. To...

    just won't idle cold

    Have an 87 lx 306 with all the goodies. It just won't idle cold .I have tried everything and just can't figure it out. Idles fine when warmed up but if it sits idling for more than 3 mins idle drops down to about 800 rpm and stays there. If I shut it off and restart idle comes up again Please...

    Fuel Is my fuel pump going?

    When in doubt swap it out. It's not that hard just make sure the tank is very close to empty. Gas is heavy. It will ease your worried mind. I didn't act soon enough in my case and was stranded. Not a good feeling.

    Help with starting issue

    There is a safety switch which prevents the starter from working without depressing the clutch. I removed mine completely. It's a matter of just taking the switch out of the circuit [ two wires shorted together]. I have been behind the wheel for many years.I always start the car in neutral anyway.

    Douchebags that want to race

    Last year I Last year I was taking my iron horse for a gallop. I was at a light when a nissan 4 door fanily car with one of those fart pipes on it pulls up next to me an starts reving his little 4 banger. He looks at me, he's about 19 and has no clue what I have under the hood. So I make out...

    throttle body ?

    By using a larger tb it will affect the port velocity. By lowering port velocity you will effect low end torque a little but increase top end hp a little .Bigger is not always better in a street car.
