    Engine rebuild

    Hey guys I have been talking to a couple of guys Here(sccheesehead, doom) about rebuild my motor or getting a different block.. I From ST.Louis, have a guy here whos a good builder.. About to get started with the build.. I told him what a couple of guys here told me about the how much hp I can get safely.. Ok he told me it sounds a little low(400-500).. So he's tell me I can at least make(500-600hp) with no problem straight motor.. I told him that that doesn't sound safe.. He had me come over so that he could show me a 1000hp cobra he just build and had a kid who had a 0 something mustang gt that he just done up and that produce almost 600hp..

    Now I want to just get the motor build good so that I can run about 100 shot of nos on it. Header,ported intake, cams, etc... All motor mostly.. Do u guys think this is safe and possible??? And is the motor 2v or 4v... Don't no to much about motor just no how to drive the he'll out them and have had and got good and big motor mostly Chevys.. Thanks Antoine .....

    There's no way he can get 500-600 streetable hp from a 4.6.

    Who is this in St Louis telling you this? 1st off there is a reason why you see all of us with power adders, So we can make that kinda power. Look at say Joe Walsh and what he got on his stroker N/A and what he is making. Talk to some guys on SVTP thell tell ya the same. Also if You could possibly build a bad ass N/A motor would you even be able to drive on the street comfortably??

    Do not build a mod motor to run it n/a. When you spend 10 or more grands on it and have a stock bottom end supercharged MM pulling car lenths on you you won't be happy.

    It's a guy (vince) who builds all performance parts plus(pat) cars... Don't no, just testing the waters before I start give Shops $$$...

    An n/a, streetable/reliable 4.6 could make 350rwhp. A streetable big bore/stroker could make over 425. You can make more but the driveability will go down greatly.

    The driveability curve and the horsepower curve intersect (in a bad way) at 500 HP in my view. The fun curve is easiest & quickest with the supercharger. Clearly Nitrous is easier & cheaper on install, but is not a street concept, more of a drag-strip use. As you know, here in St Louis we are fresh out of dragstrips.

    Conclusion: for fun on the street, talk with BODYMAN (Todd) for help putting together a S/C kit and just bolt it onto your hi-mile engine. When the engine goes south on you, then worry about coming up with one that has stronger pistons & rods, keep your old crank and do a standard rebuild.

    Yesterday, my 75,000 mile car dynoed at 490 rwhp with the small Trilogy S/C and stronger internals, stroked to 302. I pick it up next week. My guess is it will be streetable, marginally, and still feel very strong. Good luck, Antoine.

    And what is the recipe for the 350rwhp n/a motor? Is this a complete rebuild to get to that number or just a top end rebuild?

    That's a rebuild. On a stock longblock you could get 330s/340s with good torque with the right cams.

    The best way to get a Marauder moving is to increase torque by doing one of the following: advancing the intake cams, adding cubic inches or increasing compression.

    We've never seen that. It's kind of like 12's n/a on a stock long block, something that lots of people say it's easy but nobody has ever done it.

    So you saying it's not possible to make 330 rwhp n/a on a stock long block?

    +1 on what John said Antoine we could put you together a great Eaton Kit or better you should have snatched up that BNIB Vortech kit that was for sale. Then just put it on the motor you got and enjoy it till it goes south then build a stronger motor.
