588 big block mopar

The problems I see for 1000hp na wedge are two: 1. The bigger the engine, the more pumping losses you bring to the table, and 2. there are few cylinder heads that will actually move enough air to do it. You can build two 1000+hp Chevies for the cost of one mopar. If it were me I'd just go with the bowtie. Unfortunately mopars simply don't have the economy of scale to help. So it's a huge 2nd gen Hemi, or spend twice the money and 4 times the time to get the parts to build a wedge.

I said the same thing. ..638 1100hp..17500.00. Was told 22000.00 Mopar by a builder both new no used parts ...5000.00 will buy a nice glide and verta...:violent1::violent1:
 
If you can build a 1000hp Mopar for $22,000, I would be very lerry of what parts are going in it. That is way to cheap to be using good parts.

I'd have to agree. In the DIRT world a modified engine pushing 850hp and cranking 8700RPM costs about 50,000. They'll also stay together. I.e. 100 1/2 mile laps at WOT.
 
There is a fairly well developed scientific method for figuring this stuff out. The cross section area of the cylinder head and the displacement combine to set where the torque peak is. The car needs to be designed around the torque peak (or design the torque peak around the car) in order to move the car down the track the fastest.

Once you know how heavy the car is and how fast you want to go then you figure out your shift points and then figure out what your torque curve looks like. Once you know the torque curve then you can pick a cylinder head and then pick a displacement that works with the heads.

You don't start with the displacement when building a race motor, you solve for displacement. The only time to start with displacement is if the rules require it. For bracket racing most guys start with the budget and then then figure out how fast they can go and then figure out the cylinder head they can afford then solve for displacement that makes it all work.
 
^^^ yup.
Which as I said goes back to heads and budget. If you can build a competitive n/a Mopar wedge at 1000hp for $22,000.00 I'd wager there are hundreds of guys who want to talk to you.

Sorry the mopar would be 900hp..


And as far as the green hornet duster I posted it's big block Chevy powered...local race had a 604 mopar just couldn't get it done with it..so he stepped his game up..
 
Well I'm going to make a good list of what I'd like to build and see cost wise and see what direction I will go...there's a lot of will the car handle the power talk...hell I'm don't know there is only 1 way to see...who can say that any car can handle the power people put in it..it's all a test and learning curve same thing with a motor put it together best parts best builder you can find will it make power or will it blow...nobody knows. .all a learning curve. ..so I'm going to come up with a plan and go from there..thanks for all the help and I really appreciate it. .
 
I look forward to the next deal Earth... You've been doing this a while.
 
yeah your right I just have to figure out a list and go from there...

block 6000 kb/or bill Mitchell
heads 4000 b1
port 1500
rocker gear 1500
heads 440-1 port work 1600
rocker gear -1 I have td
crank shaft 900
rod 900
intake 400
cam shaft 400
lifters 600
pistons 800
bearing 250
head gasket 250
other gasket 125
machine and check 500

19725.00


this is just some prices I have found not set in stone..may have left a few things out not sure..if anybody see something that looks to low let me know or I left out a cost let me know..
 
Oil system, vacuum pump, cam drive, carb(s), more $$ for head and manifold porting, headers, dyno time...
and I'd say 800-900hp depending.

nos fogger 800
oil system I have a duel line set up with swing up on my 451 that will be used
vac. pump yes I forgot that 1000
gear drive 500
alky injected now will stay that way just set up to a terminator 600
headers I have a custom set now that was made for the car to fit so just put b1 flange on them if I go b1 or reused if -1 but about 250
id say another 500 for head and manifold port already add 1500 to the list
dyno track will be will be the dyno there are not many around here maybe 2 close by..

so another close to 3200. to the thinking out load bill lol..

1091 hp 582 18000.00 complete ready to run

I don't know I plan to spray this next motor with about 500 on 2 kits if possiable...

I'm not trying to be rude or condescending, but asking "why bother building something that big, what are you trying to accomplish" is like to asking why bother modifying your car. We could go all through this forum and ask questions like "why bother installing a bigger cam?" or "why bother building a stroker?" or "why bother installing cnc ported aluminum heads?" Why bother asking someone why they're doing something to increase power in their car?, is that not what most of us here are trying to do???

very well said!

There is nothing magic about 588 cubes. Pro Stock enignes make a lot of power from 500 inches so if someone wants to go really fast just buy an old Pro Stock engine.

They spin them things to da moon though and that means a lot of broken parts / maintenance. My 500 has a 3.85 crank and would rev to 9300+ in a heartbeat if you let it.
 
I'm in the process of building a 588 now. Not an oddball size at all. just a 4.5 bore with a 4.625 stroke. mine is going into a 68 cuda fastback.it is a street car. it specs:

601 ci
indy aluminum rb block
4.550 bore
4.625 stroke
13.5 cr gas port pistons
572-13 heads
jesel 1.7
roller 282/290 @.050 .800"
oliver steel rods
1150 dominator

I should have it in about a month. I will post the dyno results when done

exactly! a 588 will make 900-950 hp, and not have to spin it to the moon.....
 
I'm putting my 600 ' motor in this....

has a denny front end, a 3.73 moser dana 60. 4 speed also. hoping to weigh 3100-3200 pounds. should be a wild ride!

Whatcha gonna do for headers on that big motor in that little fish? How you gonna keep it under the flat hood with a 4500?

tti makes headers for it. 2" step under chassis. you can only use them with a coil over set up. I wish I could keep the flat hood. I will be using a fiberglass hood with a scoop.

I talk to a builder today and I know his work from friends and racers I've talked to and was told plan and simple. .Mike you can build a 588 with your indy heads and since I plan to spray the car anyway 1000hp want be a problem ..and not bad on parts..850hp motor and 150 spray is easy as he said..cause that's the way most seem to be doing it..I plan to go and have a seat down with him after the holidays and see what kinda plan we can come up with and a price range and we'll see how it goes. .
 
What crank and rods do you plan on running? You only figured $900 for each. A good crank is $2,500 and rods are $1,500.
