Rebuilding an 86 c10 silverado, got a 93 454 block I'm gonna build to put in it. Anyone know where I can find the OEM specs for the 93 motor? Trying to map out my build and would like to know the original bore,stroke,etc etc of the motor. And what trans would you guys recommend? Thinking I'm going the non-stroked supercharged route.
From what I head the early 90s 454 is an awesome modification to any boat. You tie a rope to it and toss it overboard when you get to your specific destination. This effectively keeps your boat from floating off with the current, thus it is called "the anchor mod".
Lol, yes I would much rather go with an lsx 454, except for the $10k price tag for the crate motor. Ballin on a budget, got this motor for nothing.
Now, anyone with some useful information?
Stock 454 from those trucks have great torque, but lack any kind of horsepower. You need much much better heads, ignition, and induction systems. Basically it's not worth the 8-10k it takes to make decent power. Basically You would be better off with a budget 6.0 swap.
My information would prove useful to those in search of anchors!
Lol very true. I'm starting with just a bare 454 block, so I will have to buy heads and stuff anyways. I'm just looking for the factory specs from the 93 454 to base my build off of. I'm going old school on the build, full mechanical, and yes a 6.0 wud be great, but I'm going a different route on this build.Quote:

Ah I remember that trucks episode, going to look it up. ThxQuote:

Not sure what other kinds of info your looking for google is a lifesaver ;)
Holy crap that CR is sooooo low. Kind of begs for boost.Quote:

Yup wrong forum but I'm still interested in the build! How can anyone not love the thought of a blown big block!

I'd venture to assume this is a truck block which has a larger deck height (10.4" vs 9.8" I think?? Been trying to look it up online, but Internet is slow at work, lol!) This makes a difference in the intake and headers you are looking to purchase. The intake has to be wider than the passanger block intake would be (or you have to use spacers). The headers will sit higher as well, so need to be a bit longer for body fitment. Luckily both options are easy to come by, it's just you have to plan for them. All internals and bolt patterns are the same. You'll also need to consider this for the front mounting brackets for anything mounting off the heads (alternator comes to mind) as it's a little different. Just thought I'd mention.
The intakes are interchangeable without spacers.Quote:
