    Opps solid ft... Nevermind.
  3. help with boat engine wont rev over 4700

    Engine Tech
    365 lbs spring pressure over the nose? That is not much for a solid roller and a heavy valvetrain like yours. 550 lbs be about right. Also need a stud girdle. I'd get that all sorted first before anything else.
  4. Blue Thunder B Valve Lift

    Engine Tech
    Unless your blower is in the way of your valve covers is no reason you cannot swap valve springs. If your blower is in the way of taking off your valve covers you have have bigger problems as any mech cam FT or roller will need the valves lashed every so often. Btw a pre worn in FT cam is no...
  5. How Big?

    Engine Tech
    Although not common there are production blocks that would take a 4.50" bore. A 4.75" stroke is about as most in a stock height block so 604ci I'd say is possible.
  6. Will I Need To Run A Cat On My '96 EFI 460 To Keep The Computer Happy?

    Engine Tech
    Did it have a second o2 sensor after the cat? If it did it will set a code if you don't have the sensors hooked up and the cats working. If it is the case you can either get the PCM reprogrammed to shut it off, or they sell a module that plugs into the harness to trick the PCM into thinking...
  7. Measuring Cylinder Bores

    Engine Tech
    Regarding pistons and rebalance if you use stock replacement pistons the weights should be close enough to not need rebalance. I've seen factory stuff be 20 grams off. That all said I personally feel having an engine balanced better is worth it even stock, but others here see no value in it...
  8. Measuring Cylinder Bores

    Engine Tech
    When you have ridge at top of bore is first clue bore is worn. Most wear is at top of ring travel as cylinder pressure is pushing rings into bore. The old cast iron rings wear more than then the moly ones. With .0015 taper you could cut the ridge and ball hone it. The result will be excessive...
  9. 498 bbc Brodix Head Hunter... What's on par 385 wise?

    Engine Tech
    Other than the P-51 may want to also look at the TFS street 325, Eliminator CJ, and AFR 300 (If it ever becomes available). What be best fit will depend a lot on your rules.
  10. What determines T-stat temp

    Engine Tech
    Dont know if still true but 20 years ago were studies that found engine wear goes up a lot below 180 f. A cold bore and a hot piston can lead to piston scuffing or seizing so always should build for the application. As for thermostat temp rating is where starts open. If cooling system is...
  11. Noise in a 545 Stroker

    Engine Tech
    I would not recommend a 4.5 stroker for a street car. A 4.3 stroke and 6.8 rod much better choice. I see a lot of what is out there is about selling parts not what right for an application. The 4.5 stroke with 6.7 rod is so you can use the same piston used with the 4.3 stroke 6.8 rod combo.
  12. 4 bolt main question

    Engine Tech
    So tell me what the 429 SCJ was homologated for?
  13. Does anyone make short fabricated aluminum valve covers

    Engine Tech
    Moroso makes a really nice set, just a bit spendy.
  14. 4 bolt main question

    Engine Tech
    Good question, but only the ones at Ford at the time can say for sure. What I do see is that they used the 4 bolt mains in applications that would see higher RPM. If cap walk is a concern then 4 bolt mains make sense. You know the 1969 Boss 302 has revised tie rods and spindles as they had...
  15. 4 bolt main question

    Engine Tech
    I doubt it. I'd say their engineering department felt it was needed to pass their durability testing and meet warranty. Most of what gets built here see's a lot less use typically and is more narrow in scope than what the OEM is concerned with. You look at what Ford did with the 429 CJ/SCJ...
  16. 4 bolt main question

    Engine Tech
    Ford put 4 bolt mains on 370hp 429's. There is no single answer. Depends on application, how careful you are about not detonating it, and how reliable it has to be. I have to say I've known a Chevy builder go 8's with a 2 bolt sbc block. I know Ford shops that build a lot of chevies and mopars...
  17. cam to much?

    Engine Tech
    You have an experienced engine builder so why not let him do his job? Tell him honestly what you goals are and what is a must have and what be nice, but not a must have. IMO that is what you should do...
  18. Like oppinions on my buddies Combo 501 SCJs

    Engine Tech
    So you saying I'm a liar? So what cu in. on the A head intake?
  19. Like oppinions on my buddies Combo 501 SCJs

    Engine Tech
    With how much cu. in.? Not really. Just some radiusing and cleaning up any casting flash. Some of those Mafia intakes need some clean up too... Well no kidding it is wrong. Think that is an easy one to see. You also don't know how that 5k converter actually is, or for that matter how good or...
  20. Like oppinions on my buddies Combo 501 SCJs

    Engine Tech
    Paper or plastic? Ported can mean different things to different people and is a loaded question just like effects of different spacers and shear plates. Not going there. I see the Victor and Mafia similar to the old motorsports A head intake and the newer TFS intake. To answer your question if...
