Don't know if any of you guys are looking for one but somebody just listed an Edelbrock B262 2x4 intake on Ebay. they say it is new old stock. cgi.ebay.com/ebaymotors/Buick-Dual-Quad-intake-Manifold-Edelbrock-B262-Nailhead_W0QQcmdZViewItemQQcategoryZ36474QQihZ011QQitemZ320232312905QQrdZ1QQsspagenameZWDVW
If the EELCO matches up to B262, the starting price should be cut in half! Sad- I had a shot at one a few months ago but communication got F'd up and someone else snatchedit up.
I'm half tempted to bid on this for the testing, so I'm not relying on borrowing someone elses. Just as an update... I am waiting for Craig (dyno operator)to call back any minute. We are trying to put a plan together to start hooking the nailhead up. I'm hoping he will be available tonight!ray: Erik
For those who haven't heard ANY dyno numbers before. We did a stock- like 401 that put down 340hp and 450 lbs/ft. That was with a stock 4bbl and a 660 Holley. There was more in it. By the simple math it should have made around 400hp. I'm doing a lot of testing here lately. If anyone would like their intakes to be tested on a flow bench, I'd like to work something out. (Marty, If you are out there) I'm trying to get some honest comparatative and quantative data as far as the best manifolds (on the bench mind you) Thanks
It would be intresting to me to know how much increase is realized by cutting the front to rear partitions out of a stock 4 bbl intake manifold. I did it and could feel a lot of difference in my 64 riv.
Doc what do you mean cutting the front and rear? do you end up with two holes instead of four holes. thanks
Hey 56, glad you joined us here!:beers2: Sounds like your R&D is producing some good results. Keep it up! Curious if you will be pursuing the rotted honda idea??? Hopefully, you guys will be offering porting services for Nailheads in the future.
56familykar- Do you have the dyno pull data saved or in a printout that you can send or post? I am very interested in seeing the graph at which RPM torque and HP meet and peak, then start to drop off. So far, I have seen nothing on paper (or electronic for that matter) on any nailhead dyno pull. I still have no hard data for comparison. Thanks
HP & Torque always cross paths at 5252 RPM's. On most normal engines that's one thing that's always constant. Tom T.
It's true for all engines, since 5252 is the constant in the equation HP = (TORQUE * RPM) / 5252. Devon
thanks all for the warm welcome. I DO have a full dyno sheet. We dyno'd this engine at our facility where I work. I will try to get a short story posted up here in the short future. It was a stock rebuild other than mild port job, 425 GS cam and Tom's Bad A$$ rockers! I am still looking for anyone who would like to have their intake tested. The test I would like to perform is purely an out of the box situation. NO porting, nothing more than bolting it up on a common port to compare to. Thanks Mike
Mike, the exhaust & intake manifolds arrived to day at 11:17 am. Did you get them???? Don't forget about the compression ratio you ended up with & the problems you ran into with carbs. etc. Tom T.
