Michael Posted July 3, 2003 Share Posted July 3, 2003 Spiirit, Are you planning on a big block for your Z? Hmm..., that would bring the BBC total on this list to around a half dozen - perhaps time for an additional forum? Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted July 3, 2003 Share Posted July 3, 2003 Nice to hear of someone brave enough to stuff Chevys biggest into one of the nicest sports cars on the globe! I am fitting a 509 into a 1983 280ZX currently using motor plates and the stock front frame. A little tight near the steering rack but other than that the fit is good. I am currently building headers and have consequently gone insane!! DEFINITELY the toughest part of the installation. I am going through-chassis style and will post the pics within the next 10 days. New avatar is of my latest aquisition, Edelbrock Victor Ram and dual Dominators.............Sanity is a matter of perspective. A full build of the car will be on the net in the next couple of months as well. I'll let everyone know when its posted. Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted July 3, 2003 Share Posted July 3, 2003 oK, YOU'LL LOVE THIS.......The primaries are 2 1/4, 25 inches long, into four inch collectors. The fit is snug. I have built the passenger side so far and plan to finish the drivers side this sunday. Yes, I have way too busy to post as you can well imagine. I started with a set of Hooker tubes I ahd kicking around and got some J-bends for peices. If there was one thing I would have done first it would have been the purchase of a large blade mitre saw, using a skill saw with a cut-off blade is very inexact as you can imagine. Flanges are cut into two peices each (two tubes per section) so they can be installed, its the only way. Drivers side will hug the steering column with three tubes on one side and one around the other. That side will have to be installed along with the steering shaft ala V8 Vega. My old website has some of the early construction pics on it although the site kinda sucks. cut and paste this into your browser: http:streetlegalmonthly.tripod.com E-mail me anytime at: b_strain@dealeremail.com Quote Link to comment Share on other sites More sharing options...
Guest Bob L Posted July 4, 2003 Share Posted July 4, 2003 What is the width of the beast across the heads??? Let me know if you need any measurements; I have a big block sitting on an engine stand in my garage. Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted July 4, 2003 Share Posted July 4, 2003 That was an early version of the engine with heavily milled (like .125 inch!) Chevv 990 casting heads. Thing couldn't hold a head gasket to save its life. I have switched to Merlin VR345's which have a nice thick deck and hold the head gaskets much better. The exhaust ports actually match quite well with the top of the tubes, the lower port mismatch just helps prevent reversion. Block is stock Mark 6 GM bored to 4.5 with a stock 4 inch HP marine crank. All the runs on the site were on the motor with the timing pulled back to 30 degrees so it would hook on those tiny tires. The new combo should be about 80 HP better in full tune. As you can imagine, I can't wait! Wrong e-mail earlier by the way, the correct one is: b-strain@dealeremail.com Quote Link to comment Share on other sites More sharing options...

Guest Bob L Posted July 5, 2003 Share Posted July 5, 2003 Thanks Bob; And just what business do you have with that big one? BBC's run from 396 to 502 right? And which do you have and why? Is it Dart or Merlin? If so' date=' how did you settle on one from the other? Tell me all about your visions with it.....LOL.[/quote'] The one I have is a 396; I'm using it for mocking up a transplant into a Porsche 928. Haven't decided if it's worth the effort at this point. Width seems no problem; the vertical dimension is daunting. What's clear at this point is that either I compromise on the engine's breathing (intake) or I'd need to run a hood scoop. I have a factory GM block, which I would not build. If I can get everything to fit; I'll go for the Dart big M block. For stroke, I'm thinking 4.25" if I go with a 9.8" deck, 4.5" stroke if a tall deck block fits. Quote Link to comment Share on other sites More sharing options...

Guest Bob L Posted July 5, 2003 Share Posted July 5, 2003 Which one are you referring to? What did it come on? Even if I keep the crank centerline where it was (~10" off the ground), I run into clearance issues with the air cleaner atop a low profile manifold + throttle body. Is there an LT1 type intake I am unaware of? Thanks. Quote Link to comment Share on other sites More sharing options...

Guest Bob L Posted July 5, 2003 Share Posted July 5, 2003 Whoops' Bob; Sorry I lit you up that way. I am sure you are more current than I. Ijust had a mental picture of the old Hilborn TPI injector manifold back in the '50s which was probably not over 4' high (without ram tubes and/or air cleaner). Hilborn is still out there and is worth a peek. Lingenfelter has a hell of a (wet) low profile ram intake manifold for around $3350.00.....LOL. Below is the one I meant you to see but alas!...it's for SBC. This guy is active' date=' perhaps he has one for BBC by now? (Oh yea. See his "Options" at the bottom). http://www.lingenfelter.com/lingenfelter/product.asp?dept%5Fid=16&pf%5Fid=63[/quote'] Not sure what lit up means, but absolutely no offense taken. At the center of the carb, the hood is 8.4" above the China wall height. A good single plane manifold is 6" tall, a throttle body about 2.3", which means the air cleaner sits above the hood. Any suggestions welcome. It may be time to mock up a hood scoop and see if I warm up to the idea. Bob Quote Link to comment Share on other sites More sharing options...
