03 Mach 1 motor build

[DSGMACH1]

Hey guys,
I am planning on procharging my Mach. I am curious what a ball park figure would be for me to forge the internals. I plan on working my way up to 700 rwhp. I know it will have to be tuned, bigger injectors, bigger fuel pump, etc... but the main thing i am looking for is the motor build.
Thanks

I'm not sure on the cost to forged internals but you might want to do some research on your block. I don't think the aluminum blocks in the machs can handle that kind of power. You might look into getting a complete shortblock and selling yours.

I'm almost positive the '03 Mach motor is essentially a cobra minus the s/c plus a shaker hood. So internals should be forged? Google it.

^I'm not sure if the Mach s internals were forged
Maybe a Mach owner will step in tho

The Mach 1 engines have a forged crank, but that's about it. The internals and block can really only handle about 450-500 rwhp, and that's pushing it. You're going to need to beef up that bottom end and internals if you're looking to push that much power.

The Mach 1's share the same motor as the cobra minus the supercharger and pistons and rods , the crank is forged , the pistons and rods will be roughly $700-$900 depending on what you buy plus the cost of honeing the block and assembly will be about another $500-$600 , I would also upgrade the heads with better valves and valve springs and a little bit more aggressive cams to reach those power #'s , your block should be able to handle that power

Mach 1 owner.

The mach engine (manual transmission only) have forged cranks. The rods are not forged and will need to be replaced with the pistons. As for the block they are WAP blocks but have been taken to 800 crank hp safely before. Do not do a bigbore stroker kit! The block will be stressed enough. You would be wise to switch over to arp2000 bolts as well. Your pistons are up to you but I like 9:1 compression which combined with 19-24lbs of boost should get you close with good tuning. I recomend buying a forged stroker kit (4.8-5.0 litres final displacement, boring the cylinders for smoothness (kits usually want .020 over which is ok) decking the cylinder heads and block. Remember that shaving the block and heads will increace compression ratio so look for a kit with a final comp ratio of 8.6-8.8 to get close to 9. Talk to your engine builder for sure... if he looks confused by anything, walk away. I would budget 3000 for parts for the engine alone if you want to do it right. More if your having it built and benchtested. Your also going to need a transmission and driveshaft. Stock stuff wont hold up.

Thanks, I know i have to upgrade everything else eventually. Im not planning on jumping straight to 700+ hp, but if im gonna rebuild the motor, i want it ready for those #s..... I was also just debating if I would be better off to sell this motor and get the cobra crate motor, or try to find a wrecked cobra... And ya, definately going to an engine builder i trust.. This is all preliminary now... I just wanna try to keep up to my buddy and his viper. lol

Tough to find a 03-04 cobra motor for under 4-5k so that being said I'd probably go the rebuild route, plus your going to have completely new parts which is a huge plus as opposed to a wrecked cobra who's previous owner for sure abused the s@*t out of it regardless of what or who they said the owner was (grandma driven etc). Plus with the aftermarket parts you'd have a better built motor for the same or possibly less cost. Just my opinion.

DaBluedude is spot on with that post.

You may want to look into a Teksid block instead of the WAP. They have been known to hold more power. Sean Hyland has done many builds with that foundation. There are a few guys at Mach1Registry that have stroked their WAP block and are making huge power. Just do some research and figure out what fits you best.

By the way the Teksids came in 96-98 Cobras, Maybe some mark 8s. Not 100% on that tho. Check out Svtp or M1R forums for some high hp mach 1 builds.

P.S please don't short change yourself on ring lands/bearings/bolts. From what i've read those are some of the first things to go POP.
