Ok guys first time out the fastest time was a 14.2 with a .487 reaction time. The car ran consistently in the middle 14's though which I was happy with. The car seems to die a little bit by the end of the track though and I am looking for a little more pull in 3rd gear. What are some suggestions? I talked to a guy this weekedn who said that 289 hi-po heads would do the trick, and I was thinking NOS, but we have cast pistons. Let me know what you guys think could maybe take us down to the 13's. Engine is a 302 bored 20 over, 600cfm Holley, Edlebrock pro-flo intake, full length headers, thats about it...Later Lox
glad to see another maverick on the drag strip!! Those aren't bad times at all. If you're looking into using 289 heads, I would suggest saving the money you'd put into making the heads worthwhile and applying it to a set of aluminum heads later down the line. About all small block ford stock iron heads are about the same performance wise...there are a few exceptions, like the '75 351w (D5TE and D5AE) and the very early 351w heads (C9OE-D0OE) which are a bit "better". Take it from someone who knows...I put about $900 total in a set of '75 351w D5AE heads, 1.90/1.60 titanium valves, fully ported, 5 angle valve job, on and on...and they still will never perform as well as my stock performer RPM heads will. Sounds like your camshaft is stock or very near stock from what you describe...a change would be in order there. Usually stock cams stop working around 4500-4800 rpm or thereabouts, so an upgrade would help quite a bit. You have a Pro-Flo intake? I don't believe I've ever heard of one. Not to say they are junk or anything...because I don't know anythign about them. We ran an Air Gap on our little 302 with great results, even a standard Performer RPM intake works quite well. Nitrous will get the quickest improvement in ET/MPH, but will also eventually get you the quickest decrease in the weight of your pocketbook. It's addictive...not to mention hard on parts.
Thats way better than my 77 which could only muster a 16.2. It has a 289, auto, 2:79's. Its pretty much stock other than duals (no headers), Eddlebrock Performer manifold, and holley 600. I've since put a set of 3:55's and a track lock. I need to get back down there & see how much difference it makes before I do anything else.
Well we have a comp cam, and I am not sure the exact name of the intake but its a edlebrock hi flow I guess...I guess if she's running ok then we'll just have to tinker with the carburation and driving techniques...other suggestions are welcome..Peace Brett
I was thinking NOS, but we have cast pistons. You can run nitrous with cast pistons if you don't get carried away and you use a good controller. I have a mild 125 hp shot and a Jacobs Nitrous Mastermind controller. It slowly brings on the nitrous and has a lot of safety features to protect your engine.
bmcdaniel I've been hoping to run into someone who has a Jacobs Nitrous Mastermind. Could you tell me what your impressions of it are? I.E. : Ease of installation/ operation, features, did you have to get a bunch of other stuff to make it work? I'm really considering getting one before I even install my nitrous and a good review may just put me over the edge. Thanks,
What mph were you running? What rpm's were you turning going through the finish line? And what rpm were you shifting at? This will all be helpfull information.
Shifted at about 5500, trap speeds were between 96 and 94 and I can't remember what the trap tach reading was, but it could have been higher I know that. Rearend is a 9" with 456 gears. Were looking at going to a carb thats two stages bigger and playing with the timing a little. We'll see next wed...Peace and keep em coming. Lox
What are your 60 foot times and what tires are you using? If you aren't pulling in third gear you may be running out of fuel on the top end, the old mech fuel pump spring gets weak after awhile, and they didn't feed a 600 holley from the factory. Do you have a fuel pressure gauge? Hope this helps Terry Gates AKA Bossmav P.S. .487 reaction time? I hate those they always send me home or back to the buy back line.
courier11sec So far I really like the Jacobs NMM, but I'm still playing around with it. You have to run an aftermarket spark box with it. That's how it retards the ignition timing when the nitrous flows, by delaying the signal from the distributor to the spark box. They strongly recommend not to use mechanical points because point bounce can cause unwanted spark. I'm using a Pertronix module in the distributor and a Mallory Hyfire VI A box. You need to purchase a fuel pressure safety switch. They used to come with the NMM but not anymore. You turn dials to set the amount of retard, rpm nitrous starts, amount of nitrous, and rev limit. The rev limiter works all the time, even when the nitrous system isn't turned on. If fuel pressure drops, the nitrous is shut off immediately. If you're having traction problems, you just turn a knob and limit the amount of nitrous flow. You can put big nitrous and fuel jets in then "detune" it from the driver's seat. Since the nitrous flows in proportion to rpm you don't empty the bottle as quick. Installation/operation is very straightforward. You can view/download manuals from Jacobs website. Sorry to be so long winded but it is a neat toy!
