Great looking Nova! I always liked that style of wheel. Sooo....that 540 is it a pump gas? You put many miles on it?

awwww come now Tod...do it right and it will be ok... :D

No runs race gas. Just a bracket car no street time. I could drive it on the street if I had regular tires on it..never have though because it's a ladder bar car with a spool. I know some do it but I'm not gonna.

i sure do Tod. thats why i got the 69 camaro and new rotating assembly, its gonna be a street warior as well.

548
 

No Fear,
I had a 540" Motor 3300lb Chevy II,it had Dart 345 Pro-1's.
My little 514 with Brodix BB-2 Extras,would KICK the S#!T out of that 540!
So,I guess what I'm saying is?Stay away from the Dart Heads!
Personally,for the Street?Depending on your Application?
I would either go with a 4.0 Stroke x 4.4500 Bore,or
a 572"er,4.5x4.5 I'm doing 1 of these 572's rite Now,on E-85.But,it will be Supercharged!
If your going Pump,you Might think about E-85,cause you can Run ALOT More Compression!Up to 14.5:1.Just a Thought.................?

I Found you the perfect motor gm 572 crate motor http://www.youtube.com/watch?v=X0INNYanWyY

Sounds cool but to much compression. Gotta keep it around 10 or 10.5:1

bbchevy I would love try E85 and try to achieve the 14:5.1 comp but E85 is not available anywhere around where I live.

I did some checking on some dealers about pump gas engines including phoning Dart to see what they said about building a short deck9.8 598ci. Dart said it is achievable with 4.60 bore,4.50 stroke,6.535 rod,zero deck 1.015 this would be a 1.45 Ratio where 1.5 Ratio would be perfect.

I phoned 2 dealers that I know build these engines and they both recommend no nitrous at all. These are just naturally aspirated engines that build over 700hp and gobs of tq. and can be driven across country,so they said.
As tempting as it is I'm still not sure if I should buy one. There are so many to choose from 540,555,565 and maybe the 582 in short decks that I can add a good shot of nitrous when I need to.

E85

700hp out of a 598 pump gas ??

http://www.nyesautomotive.net/540__700hp.html
or better yet
http://www.nyesautomotive.net/632_870hp.html

the largest arm id put in a standard deck bbc is 4.375....anyone who knows engines would most likely agree,especially for racing purposes...

when i had a motor built i had a few goals.to run 8s in quarter,93 octane fuel.that was mostly only rules.so after looking at rod to stroke ratio i settled for 4.5 stroke with 6.7 rod which nets a 1.25 piston deck height which ive heard from people that run nitrous in engines that u dont wanna go below 1.2 piston pin height on the spray...so with having a rod stroke ratio same as a 400 sbc coming in at 1.49...

ive limited my nitrous to 275 shot with current combo and i think with je pistons eagle rods and crank hellfire rings it should be fairly trouble free at 10.2:1 compression

if i could do it again id look at the dart 11.1 deck height!!!but those were not out when i built my motor 3 years ago.hell the block is only a couple hundred more and if u add up extra crank expense(ohio crank billet is about 400 more than my 4.5 eagle) of going with big big cubes like 650+ for pennies more i wished i can do it again!!!!!

in my chevelle 3000 lbs race weight so far for now best et is 8.65@154 on a 175 shot still rich so im guessing 8.50s on 175 when dialed in then load the 275 for bottom 8s so i cant complain but more cubes rock!!! :D

I got one for you http://www.sommersracing.net/Product...nster_140.aspx Matt
