The built shortblock is just the beginning of this very expensive project. |
I can raise my hand on this one, as far as a project getting really expensive that is. If you are trying to keep this one on a budget, I would suggest just getting another 3V block, stock bore&stroke and building that up. And even if you wanted to stroke it, send it off to the machine shop. When you start stroking motors, your bank account begins to reduce in value very fast. The shit gets out of hand very fast. I could own 2 Kenne Bell'd Cobras right now for the money I have in my yellow car. I SMH sometimes but I have an original build that a lot of people don't have out there, so I deal with it.

Yeah right on. I would do that but to get a stock shortblock is a few grand.
Also a gt500 motor is like 19k dollars lol. Not exactly a cheaper way out of things, then you have to do the wiring harness and all that other crap.
I just can't believe its so expensive to get a new rotating assembly installed.
I can get a good rotating assembly for like 2k bucks. Then if I could get it installed for about the same I'd be in good shape. I'd have my extra compression and internals to handle over 500rwhp. I figure if I just did that I'd go from around 432rwhp to around 440rwhp just in the compression bump. Then I figure in the extra 75hp shot of the nitrous and I'm at or around 500rwhp and 500+rwtq. Then I can squat on that for a year or so until i can afford a nice set of heads and cams to go with it all and bump her up to the 550rwhp mark.
Maybe the guys at holcomb can quote me a decent price for the rotating assembly install. I found them online for 4.6 3v for like 2 grand including balancing.

I'm now also considering going ahead and just upgrading my fuel pumps to the gt500 set up and bumping up the nitrous pill to a 150-175shot. That will take me up close to the 500rwhp mark. Given I don't race much and don't really use the bottle a lot I think the stock short block will hold up until I can afford to just go ahead and buy the new shortblock and afford to get it installed.
Only thing i"m not sure of is whether or not my stock injectors will be able to sustain the extra spray. I emailed my performance dude so I'll guess I'll wait to see what he says about it.

Yeah but why mess with another 7k dollars when I'm 60hp away from 500rwhp as it is.
A supercharger is expensive, and then add in a meth kit on top of that with labor your talking in excess of 7k dollars, which is the same amount I'd spend on a shortblock with install or a forged rotating assembly and have a block rated at 1000hp and numbers over the 500rwhp marker.
I'm a nitrous guy too, I love me my spray. And it would take someone giving me a supercharger to take off my nitrous kit and start with a s/c package.

Yuppers, thats why doing a supercharger and meth kit won't really solve anything for me. The whole point of doing the shortblock isn't necessarily to gain hp, its to allow me to further mod and get hp without smoking my stock shortblock in the process. the stock shortblock is only good to around 500hp then you run the risk of bending rods and effin up your pistons, etc. I think the stock crank is good till around 600 but why risk it lol.

As far as getting your HP in the high 500's, you have to start looking in other areas that are taking the punishment. First and foremost I would be concerned with the transmission/drivetrain. All the supporting mods to the power is where the money isn't really thought about at first. Also, I know you were already talking about needing a better fuel system. Def. need 2 pumps, and/or a boost-a-pump. Fuel systems cost an ass ton too. Mine personally is a lil more than that, but ran me around $1800 after all said and done. But I think you can get away with it costing you around about $1k
