Take my advice, afterall I have one with the e-cam.
The engine is alright, but like others have said or will say, you can get more hp for the buck if you do your math. My car was stolen the motor was blown and I needed a whole new block (b/c there were some holes in it)-never mind heads/other internals.
Now if you start out with a solid block, you can get a much better came from Ed Curtis, AFR 165 heads and a Edelbrock Intake and pretty much blow everything away (with the proper CAI, Fuel, Exhaust upgrades)
This is THE combo to have. It gets you the best bang for the buck and I regret not having it.
Now about the engine you're considering.
Besides the fact that I have beat the bag out of it untuned for the last 20,000miles, its got some significant weaknesses.
Your computer will hate the e-cam or b-cam
It has weak internals, hypertunic (spl?) pistons suck!
Get a 92 or older block, they come with forged internals so should you feel the need for boost/n20 you're set!
The heads are ok, but for what you end up spending on them you might as well have the best-which offer significant performance over the gt40x's.
The best track time I've had was a
[email protected] with my t-5 and 3.73 gears on street tires. Now there was room for much improvement except I shattered my trany on the next pass. If you can drive and you dont have a vert you can get into the 12's on street tires-provided they're not cheapo's. I still havnt run it with my (killer) viper spec t56 but its probably going to be slower because of the gearing.
I hope this info helps you out with your decision. I think I've covered most if no all bases but should you have any more questions feel free to PM me. My mods are in my sig. and IF you really want to go with this combo the one good thing is that my exhaust note is super loud. It hurts my ears sometimes and at my 1,100rpm idle-the lowest I can get it, it sounds badass.
Do your research, ask around for the AFR, Ed Curtis, Edelbrock combo.
