    OK, now I know my block is a genuine 454, and can support additional 0.030 overboring, I'm thinking of building a stroker motor. 4.28" bore, 4.25" stroker crank yields a 489ci engine. /forums/images/graemlins/eek.gif /forums/images/graemlins/grin.gif Connecting rods are stock length 6.135", 3/8 ARP rod bolts, rod ratio winds up at 1.44-1. Compression ratio will be 9.5 using TRW hypereutectic pistons. Heads are oval port "781" castings with 2.06 intake and 1.72 exhaust. Thinking of using Competition Cams extreme 4x4, haven't decided on a grind yet. I saw some good posts on those awhile ago, I'll have to try and find them again. /forums/images/graemlins/tongue.gif

    Does this sound like a good combination of parts to build a reliable, low rpm torque monster in a daily driver to you?

    Any recommendations on a cam, (Q-jet and dual plane intake is being used) or changes you would make?

    Everything sounds like it should work well together. For a intake manifold, I've always liked the Wieand Stelth.

    that looks pretty good. Here's my plan:
    https://www.jegs.com/cgi-bin/ncommerce3/OrderItemList?Krypto=8OT5fiZwwtnYc6dZAFwT77pnKUa3ssF7RxuXWLz8cNkrWpZ%2B7ozBfCopmuwrqEYPp%2BhVkg3z3lbyqSiUMF0H%2FrprmNFYBXpxIbBbI%2BnwkAlCQNWPOA2L5tEbcXSwAnSMRrf4ll2%2BOkJiY%2BWWx8QH6jQcgYuX2hIG%2FpA5lw86D%2FrAKmhFx8O%2B0euZYnGmjaFb

    That will be over the course of about 4 years- it's my next project, instead of building a new truck, build a new engine for my truck/forums/images/graemlins/grin.gif I want this to be so powerful that I can go to the track and race them freakin ricers and stangs! Let me know what ya'll think!/forums/images/graemlins/grin.gif

    With the 4.5" bore and 4.5" stroke it'll be a 573 /forums/images/graemlins/eek.gif/forums/images/graemlins/eek.gif (572.5)

    I'm counting on about 1000hp/forums/images/graemlins/grin.gif

    nah. i can't afford that much at once, and i'm terrible at saving- so i need a build plan and buy parts and build slowly, plus a EFI 502 ain't near the same power, and it'll still be about 8k. the closest thing would be a world 540 with 800hp, but that's 11k. plus i wanna say look at my built engine. like they say, built not bought. i'm not ordering any of that now. and i probably won't use all those parts. this summer i'm going to hunt down a good used 454 block and bore it .030 over and do some clearancing for a 4.5 stroke. i may leave it at 454, but it will be a blown BBC with 12:1 compression atleast. i will have ponies!

    Ya might want to do some more reading about superchargers before you build an engine with a 12:1 compression ratio and then try to slap a supercharger on top of it. That's a recipe for disaster... /forums/images/graemlins/shocked.gif /forums/images/graemlins/eek.gif

    you know, i hadn't even thought about that. you're right. i'll have to make a decision. 12:1 or blower.

    Personally, I would ditch the 3/8" rods for 7/16" rods...I got a smoking deal on some Eagle ESP rods...More often than not, whan a BBC lets got big time (ie a rod through the block) is a result of a rod letting go...That is why I spent th eextra cash on good rods...Good choice on pistons...I chose the SpeedPro Hyper that have the coated skirt...The hyper design and the coated skirt allow a tight piston-bore clearance; as tight a .015".Whast kinda dome are you running to get a 9.5 CR with 118cc chamber?

    The heads are pretty good, but can be pretty AWESOME with some work. Check this thread out on 454ss.com some good info on the heads Obviously, some Edel 6045 or similar will make an outrageous motor /forums/images/graemlins/thumb.gif



    For my torquey 454 motor build I am using the following...

    -Stock 454 Gen V block bored over to 4.280"
    -Stock crank
    -Eagle ESP h-beam rods with ARP 7/16" WaveLoc bolts
    -Speed Pro Hyper pistons, Flat top 2VR, coated skirts
    -"156" "peanut port" heads, shaved .010", valve job
    -GMPP Truck Torque cam, basically a Crane 2020 cam, low duration and lift, good for torque down low
    -Edel timing chain
    -stock TBI manifold
    -Comp roller rockers

    Had the entire rotatin assembly balanced...should be a pretty reliable motor...

    Good luck

    Chris

    As far as heads are concerned, might want to check out World and GMPP BBC Vortec heads.

    Don't waste your time or $$$ on the BBC Vortec heads...the SBC vortec are simply amazing, but the BBC's are "run-of-the-mill"...World has some sweet things, as do Brodix, Dart, and AFR...I would stick with an oval port head to keep the intake velocity up to aid the low end grunt... Shawn has the Edel 6045's on his 496 and that focker moves...I am currently collecting parts to build a beefy 496 and I will be using the Edelbrock 6045 and Holley MPFI...

    For a cam, call comp and talk to their tech guys and they can recommend a cam that will suit your needs...

    I believe the dome height is 0.09 or 0.1something. I don't intend to rev this motor over 5500rpm, so I think the 3/8 rod bolts will be ok, they are ARP ... but maybe I should see if I can upgrade to 7/16.

    Money issues will keep the heads basically stock for now, but I think it will still produce plenty of torque & power. In the future, I would like to run a fuel injection setup, but that is a long way off.

    The vortec big block heads are redesigned and are much better than any other factory head. They have a much better exhaust port than they use to have. If I was building a 454-496 I would use the peanut heads and do some pocket porting and major work on the intake plenum. I believe that you can make 450hp with this head at 4500-5000rpm's. I can not see you needing anymore rpm's than that.

    Should just get a loan and go ahead and buy the 634 cubic inch BBC from Bill Mitchells Hardcore Racing.....The same guy who made World Products famous. /forums/images/graemlins/wink.gif

    This motor will make up to 700 or 800 ft. lbs. of torque! /forums/images/graemlins/eek.gif /forums/images/graemlins/thumb.gif

    Also check into the World Products Injectorator system rather than a blower. With a blower, you will need to divert more attention to it and have to have tighter tolerances for everything internally-wise. An Injectorator will be more of a maintenance-free part so you can enjoy turning the truck on and driving around more often. /forums/images/graemlins/thumb.gif

    check out the latest Jegs catelog (not on the website yet, or on World's website) and you'll fing "Hardcore" crate engines from world, the best is a 540ci, fully ported, aluminum heads, roller rockers, etc. with 800hp. mine would still be better/forums/images/graemlins/grin.gif

    Ahhhh...I see you are after horsepower rather than torque. I would say you would be much happier off with a torque monster engine rather than a horsepowered engine. Think about the hard launches you can do off the line or green lights. Think about all that raw torque at way down lower RPM's. /forums/images/graemlins/wink.gif /forums/images/graemlins/thumb.gif Think about pulling someone out of a stuck situation. Think about pulling your buddy's rig during a tow-down. /forums/images/graemlins/thumb.gif
