Car: 89 GTA Engine: 5.7L Supercharged Transmission: T-56 Axle/Gears: Moser 9" 3.70 | You got me real interested here, do you have any max HP numbers that both the GM and Motown blocks can take? Also this Motown block that these guys assemble is it all forged? |

Car: Death Mobile Engine: 666 c.i. | I use to have them on one of my old dead computers, but I cannot find them  The production blocks were rated surprising low and the numbers came from GM own website. Try the GM Performance Parts website. Obviously they were promoting their "Bowtie" blocks which are also good blocks, but quite expensive and jsut a bare block.
The Motown 454 (and this is not their Hardcore Racing crate motor either) produces over 610 HP @ 6,400 rpm - and is dyno tested before they box it up and send it to you. I beleive every crate motor includes the dyno sheet of what the engine produced.
Considering the 454 is a REAL thin bore (4.250)" vs 4.125" for the 427, the 427 should be a little stronge yet. I just love the thought that the 427 CAN be bored out to 4.200 and become a 443. That means you can go safely go .075" over. I don't think you bore the 454 much more. They claim on the 427 with it bored to 4.200" there is still .250" between the cylinders. That means a 454 has only .200" left between each bore (now that's thin). I don't think it will be going ".060" over.
I like the idea that I can rebore my engine a few times and still use it. I also think you can increase the stroke a liitle more also and swap in 4 1/8" crank...but don't quote me on that one. The 4" crank is really getting close to the cam location and I think you may have to use a smaller base circle cam if you go over .550" lift (which most solid roller do). That's okay, on solid rollers, most of the real wild grinds are on small base circle cams anyway and you must go billet steel.
Hell, Comp Cam stopped producing "cast" solid roller cams just recently (maybe too many failures)? When my buddy ordred his solid roller last month, they told him that they no longer produce that grind in "cast" and he had to buy "billet steel". Based on some of the failures I've seen on Comp Cams, I now know why. It was only $75 bucks more. When you are dropping thousands of dollars, it doesn't pay to "cheap out" on some of the critical pieces.
And, to my knowledge the entire rotating assembly is forged. Here is a techcnial blurb on the completed crate motors. I would consider one of those, but I can swap on AFR 210s (their Motown 220s don't flow quite as nice) and a solid roller cam with a little more duration onto their shortblock for less money and make more power.
They use to provide ratings (now they give the purchaser their own personal dyno sheet). As I recall the 415 was rate 465-485 (depending if iron vs aluminum head) and the 427 was rated 505-530 (depending on which head you chose). And this was both a realtively small flat tappet cam in my opinion.
The only difference between the street crate and racing crate (besides the price) was higher compression 13.5:1 forged pistons and a bigger solid roller cam. There is "some difference" between the blocks too, but I have yet to see any technical differences other than splayed mains versus regular 4 bolt mains....but my eyes are bad. The engine was rated 675 HP.
I'm looking for something "in between".

Umm.. so your in Salmon Arm now.. . A good friend of Mine lives there. Drives a "Bright White" Dodge Ram Charger. I helped him do all the body work, and paint it.

During winter, I stay pretty close to town, even with my beater car. If I have to go down to the Coast, I find it cheaper to just rent a car and put it on my Platnium Card (which carries it's own insurance). This way, if the windshield gets cracked, I don't spend $200 for the deductible.
The first year we moved to Kamloops in 2000, we were saving for a house and didn't have a beater car. I was forced to drive the GTA during winter and my hood took a total beating and needs to be completely repainted now.
Unfortuately, I won't be driving the GTA until I go down to my buddy's home in the US and pick up my parts (cam, timing set, etc). The timing chain needs to be changed badly (you can actually hear it slapping), but with 300,000+ kms, it owes me nothing.
BTW, how do you like Salmon Arm? If you ever get out to Kamloops, give me a shout. | |

I'm really only driving it because it's the only one of my cars that's actually in operational condition right now. My daily driver car is having ignition problems and I have to wait for the ground underneath my truck to dry up enough to put a new transfer case in.
I'm in Kamloops right now, actually. I'm here pretty much every weekend. Salmon Arm isn't so bad, it's considerably more tolerable than it was when I was working there a few years ago. | |

Car: 91 Firebird Green Engine: SBC L03 - TBI 5.0L V8 Transmission: WC T5 | Here in Winfield, going to school at OUC North in Kelowna. There area a TON of 3rd gens in this part of the province! I just moved down from Prince Rupert in late August, I think there were less than 10 3rd gens in the whole city when I left
Anyhow, I've been chatting a bit on this board for about a year now (since I've owned my 91 Firechicken) and just wanted to give a shout out from Winfield to the rest of the BC members. 
Oh, and anyone see a gorgious blue and red camaro in the area? I caught a glimpse of it a couple days ago... My *** it looked incredible.
As for my firechicken, it's in good health as of this afternoon when I installed a new TPS... I guess the old one wore out. | |

Not a recent image. This was the day after she got her new green coat (wrong paint mix from Acklands). I'm living with it for now... | |

Car: 91 Firebird Green Engine: SBC L03 - TBI 5.0L V8 Transmission: WC T5 | Just wondering if anyone from the BC interior would like to get together sometime this spring and race our third gens on a drag strip in the area. I only know of the one just out of Kelowna, near Big White. I havn't ever been to a strip before, so I'm not sure on the rules and such involved with renting it, safety measures etc. etc. just and idea....
I doubt I can break 15 seconds It would be fun though. | |

Better would be Ashcroft (about an hour west of Kamloops on the TCH) or Mission. | |

Do you think you might be interested? (As well as anyone else?) | |

The good news is I get lots of overtime to pay for it. I'll be available to tag along to Ashcroft any time you guys want to go, though. | |

I would be up for doing it in May if anyone is interested | |
