To Ragen' Rat638, if you wouldn't mind could you send me a mod list of what's in your 638? That'd get me started in the right direction anyway. Have you ever had that 638 on a dyno? If so, how much?

Well all I have to say is

.

Holy crap RAGENRAT, the motor sounds wicked. Gave me goosebumps listening to it.

Good luck with your project bhunt31. Anything would be cool with a 638 cid engine in it, especially a Chevy truck.

just my opinion- if your going to spend that much coin on a motor of that magnitude, why wouldnt you try to get all the power out of it you could? You can make 500hp easy on a supercharged 350 for a fraction of the cost. again, just my opinion.

I agree but, come on, a 638 cubic inch big block???

Just my opinion but when someone hears the roar of your truck pulling into a parking lot, comes over to check it out and asks "Oh my god, what have you got in that thing?" What is going to sound cooler?

A Supercharged 350

or

A 638 cubic inch big block

Just something about a Big Block. Plus I won't have the whine of the charger giving things away. Just the shaking of the asphalt when I roll up. Also, the way I am, if I'm gonna build a big block, I'm gonna build a BIG block. I wanna keep the cam tame so I can actually drive it. I've got a monster cam in the 350 in my 84 Silverado right now and it's nothing nice to try to drive around. It puts the idle at 1200, so yeah...it's coming out soon. Cool thing about it is it'll slide the back end sideways at 90 in 2nd gear,

, but it's my daily driver, so that's no good, and with the 3" pipes and FlowTech Afterburner Mufflers and small tube headers...it wakes cops up when I drive by(not good)

A mild 638 will be way more streetable than a supercharged 350 and run just as good. It's all about the inches.

ThatOneBlue67 · 02-28-2007, 12:41 AM

How about a 638 Supercharged?

bhunt31 · 02-28-2007, 01:47 AM

you're gonna get me in a lot of trouble....that's a really good idea though....what am I saying? am I

? haha, yeah, I'll have to set the shortblock up to stick a blower on at a later date......

I enjoy a big block I have two but a friend of mine is sticking an all aluminum 638 in his 57 Chevy pickup I told him he is crazy because the 600Hp 396 he has now scares the hell out of me. Well good luck and I look forward to your progress.
