    Fuel Efi Block Into A Carb'd Stang

    early timing cover for mech pump. what mechanical intank pump are you talking about? in a carbed car there should only be the pickup and the sender for the fuel gauge.

    it runs 6.30s@108+ so far on the motor running mid 1.3 second 60' times. they are some 1971 Cleveland heads. the cam is not small.

    ok. ill play. first I want to say this: a real 500rwhp 3200lb fox done right is a freaking beast of a street car. so much so that it might kill you if it wont hook up and wont stop. I have pleanty of friends that have quit messing with cars when their 400rwhp blower 302s gave them a taste. now...

    so a 302 cylinder is like a glass 4" wide and 3" long. for all intents and purposes a 408 is still a 4" wide glass, but now its 4" long. if the bottom of the glass moved up and down and you have a seal at the top of the glass and nothing can get out; since the 408 glass will hold a greater...

    Engine Stroking My 302 To A 347, General Questions.

    I like 347s. the last one I played with ran hard. 6.40s@105 on the motor at 2900lbs in the 1/8th. the 408 im messing with now is about a tenth quicker and 3 mph faster in the 1/8th and about a tenth quicker in the 60'. the 347 is much easier to get to hook. but....if its a street car the cubes...

    1/4 Mile Issues

    with your car I would expect to see 115+ mph with that kind of power assuming its 3200lbs or so. could be something as simple as how the valvesprings are setup. a couple little simple things can kill an NA car. its tough to shake it down away from the track. 110mph is good for 12.20s though.

    1/4 Mile Issues

    ive gone 6.80s@98 in the 1/8th (high 10s@122) with 340rwhp at 3000lbs. so no, you don't need 400 rwhp to go 11s at 3200lbs. this particular 302 made 310 and trapped 115 mph. there are guys who have gone 118 mph in the 1/4 with unported gt40 irons at 3200lbs. NMRA factory stock guys used to...

    you do realize you have to have a well prepped track, a decent suspension and tires (it also took a 10" wheel with 28-10 MT slicks to hook up my buddies all motor 408) to hook a 500rwhp NA combo, right? if you are going to use a stock block do yourself a favor run a 4.0" stroke (408-410)...

    3200lbs with driver and a 6100 rpm shift point with a fresh 91 5 liter shortblock. im simply trying to help you understand that the world is not flat. how much more specific can I get when I ask you what your target airspeed number is and what do you define as oversized? I know the airspeed...

    1/4 Mile Issues

    and what do you define as oversized? bigger than what your calculator says it should have? what do you define as target airspeed? perhaps your builds that you are saying that don't pull as much air as they should is because you are putting a big fat cork in the induction system? maybe if you...

    1/4 Mile Issues

    once again, its not about cfm. its about finding the best venturi size for the appication. does it run good with that carb? yes. would it pick up more mph with a nice carb? I am so sure it would that if he lived close to me and wanted to try it, I would be willing to put the unported 351w vic jr...

    Fmu Question?

    IIRC (because I haven't used an FMU since about 98) yes boost will push on the calibration plates which push on the piston. I have a couple of those early vortech and Paxton fmu's as well as an old cartech adjustable. they are just taking up space in my tool box, for a long time.

    the carb has its downsides. but ive gotten used to changing jets. if I had a driver with a carb it would be a pain in the ass. but in terms of getting down the track its hard to beat a good semi/custom carb.

    Fmu Question?

    when you say rebuild did you just replace the diaphragm or did you take apart the piston too?

    Fmu Question?

    if you hook it up backwards it will spike the fuel pressure through the roof constantly, at least if its like the old vortech, Paxton and cartech fmu's. so you probably have the fuel lines hooked up correctly in terms inlet and outlet of the FMU. it has to have boost signal from the vacuum...

    There is a reason I have provided links. I know what has been explained to me by some very knowledgeable people, and everything they have explained to me has worked. I didn't even get into the differences in metering and emulsion. there is a reason some carbs run better than others. from a best...
