Hey guys any input or thoughts would be appreciated.

BBC 454 .060 block
Scat crank and rods with Srp lightweight pistons
Doug herbert solid roller .642 285 diration cam
gear drive
188 cast rectangle port heads fully ported 2.19 1.88 valves
harland sharp 1.7 roller rockers
holley strip dominator
holley 850 dp
all hooked to a (about to be destroyed) saginaw tranny and stock rear end. Plans are to rip through the tranny and shove in a muncie as soon as its checked out for me. Id like a 9 inch to go in back. As far as the engine combo what do you guys think and would you have done anything different. I'd like 600 true horses out of my combo

oh yea it currently has 1 7/8 heads and 3 inch exhaust with an h pipe flowing through flowmasters.

What's your ET goal?

I really don't know i'm twenty now i've had the car since i was 16 and i've been putting so much time and money into it I really never sat down and thought about it. I'd be happy with low 11's

If you are going to run a Manual Trans, don't bother switching the rear end if it is an 8.5" 10 bolt. If it is an 8.2", go right to a 12-bolt rear and save your money on the 9". You would break the Muncie before doing any hurt on a properly built 8.5 10 bolt or way before hurting the 12-bolt.

Just curious...
Since you've had to purchase a new crank, rods, & pistons anyway, why didn't you go with a 4.25" stroke and make a 496? :confused:

as they say, poor boys have poor boy ways..... graemlins/clonk.gif

I'm going for a 489......

454 bored .030 with a 4.25" stroke crank. This appears to be my easiest way to more cubes. I already have a set of 4.28 KB domed pistons and all I need to do now is replace the original GM 4" stroke crank with a 4.25" stroker. Anyone have a suggestion for a source for the crank ?

Todd, ask the long stroke guys how fast their tire smokers are. I guarantee your 414 is faster. Unless you have a real race car the torque of the 4.25 and up stroke Big Blocks isn't really usable for anything but smoking the tires.

Unless you have a real race car the torque of the 4.25 and up stroke Big Blocks isn't really usable for anything but smoking the tires I'm certainly not even close to the most knowledgable around here, but I can tell a HUGE difference in my new 462 vs. my old (well built) 408..... I'll know the actual time slip difference in a few weeks. The guy that did my head work said the 496 vs. 468 was good for a tenth or 2 in the 1/8th mile, but I would think the better your suspension is, the more you would benefit from the torque. Am I wrong?

EDIT:
:rolleyes:

You can smoke the tires with a 427 or a well built 396.

Hey, back to point, Muncie, solid roller?? How you think that is going to last? Let me tell you, I really don't think its a good long term solution. You'll need more than a Muncie , or Manula, as Tom says ;) . The Sagniaw isnt going to last but a few powershifts. The Muncie might be good for a few seasons, but slicks will hammer that down.

Well, I could point to a number of long stroke guys who are faster than Todd. Likewise, I could point to a number of small block guys who are faster as well. It's all about the combination - not just displacement, rod/stroke ratio, etc., and you don't necessarily need a 'real race car' to run quick in a long stroke BBC. Keep in mind that different people have different goals.

Not at all a bash on Todd's car - no question his Malibu is fast. I just feel your statement in general, and guarantee :rolleyes: , was a little provocative and misleading.

427L88, thanks I think your one of the only ones who actually answered any of my questions! :D Mostly it's gonna be a street car I just firgured if i was going to go through the engine i might as well do it right.

I know this is an age old question but what kind of hp and tq levels should i expect from this combo, the ol' 68 needs a little pick me up :D

You're going to need 13.5+:1 compression to run 285 degrees of camshaft - IMO - and if you're going to run good fuel - you might as well run good springs and put some lift to it.

What I was getting at was many here feel a 496 is the hot ticket to quicker ET's or serious street power. Well, those same people also likely don't take into consideration what it takes in respect to chassis setup & mods to attempt to hook the large torque output efficiently. It ain't easy and requires some meticulous work in the chassis department to hook up. If you have a stock or newar stock chassis, you'll never see the full potential of the increased torque of the 496.

On the street side of the subject, the more torque simply makes the smoke screen behind you that much larger...IMO, it don't matter what size bbc you run on the street as with street radial tires, you ain't gonna hook anyway.

I never said my ride was faster than anyone else's...those were Mike's words.

I can make one guarantee (at least I think I can :rolleyes: )...put a 496 in a modified/stock suspension Chevelle and put it on drag radials. I'm confident that you WILL NOT hook consistently on the DOT drag radial tires without the aid of a timing computer/retard (which I DO NOT make use of).

STROKED IS NICE BUT I'D RATHER BE BLOWN. :D

Wow, interesting responses to a pretty straight-forward question.

Really, its kinda like in math class - there are often multiple ways that a particular answer can be obtained.

Consider the age old hot rod dictum: power to weight is what it is all about. Some Malibus weigh less than others.

Next up: getting all the power to the ground in an efficient manner. Tell me who here is going to build a thumping big block and then cripple it with stock suspension. All the guys laying down quick times, no matter what the cubes etc., have spent time and effort on chassis setup and torque converter selection. A consistently quick stick car will not happen naturally.

You'll get there, and along the way to your goals you'll also change a few parts.
