    new 408 low dyno numbers

    Well let's see. 1. Way too small of a cam. 2. WAY too small of headers. Get rid of the shorties. 3. Way wrong intake and carb. Get a vic jr (or at least a perf rpm or similar if you have hood clearance issues) and call pro systems for a good holley based carb. 4. Heads are way too small...

    Front Coil Over and 60’ times – 65 Mustang

    Wrong, c/g has a HUGE affect on the launch. I have just been through this with my car. My car runs high 10's. I have talked with many of the top chassis shops and they all say the same thing. I know I had stock 6cyl springs in it last year. Car sat real high but lifted the tires about a...

    408w aluminum block, Mass-Flo EFI, ordered from TandL

    Sounds awesome! Now I just hope you also have the chassis, suspension, transmission, rear end, drive shaft, u'joints, axles, etc, to handle all this extra power.

    Preliminary dyno results

    It would have been interesting to see back to back results. But nice build! What cam specs do you have??

    what shifter for your C4

    Depends on if you want a ratchet or not. I really like my quick silver. But I also like my stock one in my other car also.

    FMX rebuild or replace ?

    Find a good small local trans shop. I have them done for $300-$400. I would just have it rebuilt.

    New Engine - FR, Keith Craft or Smedding?

    Just keep in mind, a dart blocked quote will be WAY higher. Dart blocks start at around $2000 for a bare unfinished block. With the hp you are looking for and if you don' t plan on power adding it, it would be a waste of money. Stock block will handle what you are planning and then a bit...

    Thoughts on Demon carb?

    :bs: I am a machinest so I know what I see. And I seen Many demons apart, and heard from other people as well. Sliver? Are you kidding? As soon as I took them apart, I would just tip over the metering blocks and bowls and I would have a PILE of chips on the bench! A couple of people I know...

    408w 185AFR setup...

    Yep, I agree with everyone here. 185's not bad at all. Trans is depending if you want to shift or not. I have been through a few sets of rockers and by far the best bang for the buck and toughest I have used are the pro comp magnums. Vic jr or perf rpm air gap would be the best but you might...

    boss 429 vs 428 cj?

    Traction loc questions

    My guess is the clutch packs are shimmed a bit too tight. That is what I did to mine, although intentionally. I shimmed mine up tight so at the track, when I am in the water, they will turn both. I had trouble with this alot. They will definately wear much faster like this, but I have had...

    Frame rail/torque box/firewall replacement help

    I'll try and answer your question. I have replaced the floor pans before on different cars. I think the firewall will be fine. The toe board will cover most if not all of that. If it does not, I just used the sheetmetal left over from trimming the floor pan to weld in between the toe board...

    351w header options

    MY suggestion would be to NOT buy the accufabs. I just bought some. Absolutely the biggest pos I have ever paid for. And VERY expensive also. None of the bolts would go into the holes, and this was even before I put them up to the heads! Found 2 big leaks. The one side, was pointing...

    Demon blow thru question.

    Not saying demons are no good or anything, but you really should take it apart and clean it good. My buddy bought one, (and have heard of ALOT of people having the same thing), and we took it apart and it was FULL of aluminum chips! Take it apart and clean them out first!!! Since, it has run...

    The engine builders "black art" (AKA Rod ratio)

    If you are building an all out, no expense, high rpm, race motor?? Then I would definatley look into it. But otherwise??

    "Budget" 351W Build

    Sounds like my motor in my mach1. Stock bottom end except for arp rod bolts. Cheap stock compression hypereutectics. Stock heads that have 1.90, 1.60 valves and were ported by me when I was like 16 and didn't know what I was doing. Perf rpm intake, 1 5/8 headers, and a junk rusted 750 that I...
