Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 heads are a tad on the big side IMO, for the mild cam and intake you have on it. a much better dual plane is out there that makes all kinds of power, thru the whole rpm range. and the cams not so weak, just low on the lift numbers. now with the 4.11's, what size tire you plan on running and how hard are you planning on spinning it? (rpm wise) are you looking to build a max effort drag car thats streetable? Quote Link to comment Share on other sites More sharing options...
TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 to be honest I am going to be building a bbc over the next 1.5 years, a nice planned out 496, I am just tired of that old 250 6cyl in the car lol. I put on some 255/60/15 radials on the car, I plan on just cruising and getting into it between lights. I am thinking 4.11 would be a great gear for that cam and to get some use out of the heads. this dyno from comp is damn close to my setup less the intake http://www.compcams.com/information/Products/Camshafts/DynoSheets/XE294H-10_001.asp I know there are some better dual planes but on my cheap budget I pieced alot together by wheeling and dealing and this intake came with my short block. and the heads I picked up for 400 and they sell for 550 each so could not pass it up. maybe spinning max to 5500-6k Quote Link to comment Share on other sites More sharing options...
TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 so a 750 dp from holley or a edelbrock 750, how much difference would I notice. Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 750 holley..the bad about the dlebrocks carb is the jets sit in the bottom of the carb..i have seen cars fall flat on there face clicking second cause the fuel moves away from the jets... 255 60...how tall is it? 4.11 will wake it up, but that intak egives up around 5500, and if 1/4 is in mind, you may just be winding it harder then that.. get the actual tire hieght and use the calculators i posted in the tech help forum in the sticky at the top to help figure gearing.

TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 sweet i appreciate it. So what holley 750? just a double pumper...or do you suggest vac sec? I have seen a few but trying to stay away from paying out for a new carb. Anyone rebuild carbs on here or at least go through to check them out? prices?

Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 annular discharge.....thats looks like a older 4150 pro..it would do work, and seems like a good price..but how high is the bidding going to go Quote Link to comment Share on other sites More sharing options...

TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 never had vac sec. are they good or bad to look into for my engine Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 well if hes doing a strong 496, then he will need a dommy 1050. Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 never had vac sec. are they good or bad to look into for my engine they are great for a light car. 100 different ways to tune it and build it any way you look at it Quote Link to comment Share on other sites More sharing options...
65belairpost Posted April 13, 2009 Report Share Posted April 13, 2009 well if hes doing a strong 496, then he will need a dommy 1050. Well mine is pretty healthy and the 850dp kb does a fine job.... Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 and like i stated...a healthy 496(aka big head roller cam and so on) will need more. 850 will do fine for street duty if set up right. i know one i was working with had a 950 pro on it, and the car picked up a ton in the 1/4 with just the intake and a 1050 out of the box.

65belairpost Posted April 13, 2009 Report Share Posted April 13, 2009 Sounds like some good info...what kind of horsepower and torque was that motor putting out? Quote Link to comment Share on other sites More sharing options...
Guest Removed Posted April 13, 2009 Report Share Posted April 13, 2009 not sure on power numbers..but it went from 11 teens with the 950 to high 10's with a 1050 and a adaptor...then it went mid 10's when they finally stocked the brodix 4500 intake,once the carb got dailed in.. and that was a 3400lb g body, with a turbo 400, 9" etc etc..

TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 I think i might try and bid on the dp on ebay if I can get it under 200 shipped that would be a great deal. what would commonly be bad if anything? Quote Link to comment Share on other sites More sharing options...
tomcowle Posted April 13, 2009 Report Share Posted April 13, 2009 Fiero, sounds like a nice combination for a street/strip car, clean up that intake a little and your fine. If you can swing it, get a HVH SuperSucker 1" spacer and that will add some needed plenum. 4.11's would be my choice for your set-up on gears. 750dp holley would be ideal, cheap/easy rebuild kit it and your racing. 2nd choice 750vac sec with an adjustable spring kit.

TurboNova Posted April 13, 2009 Author Report Share Posted April 13, 2009 Thanks, I ended up with a 750dp and it is over at robs getting a kit installed in it. I just need to figure out the gears now Quote Link to comment Share on other sites More sharing options...
TurboNova Posted April 14, 2009 Author Report Share Posted April 14, 2009 Is there a cruising calc? if i have 4.10 gears with a 27in tall tire..... with a th350 what would I be cruising the highway at Quote Link to comment Share on other sites More sharing options...
