Yes, spring 2011 is when it should actually drive but it might make noise fall 201 I got my grinding done. Machining the flanges tomorrow I guess....although I probably should touch up that drill nicks befer the machining.....welding tomorrow I meant to say.
After more looking and comparing between the 2 heads I decided the best answer on the bottom of the ports was to grind not weld. I did weld up the little nicks and started the finish cut on the flanges .I cleaned up the first one but the second didnt clean up at the same height so now head 1 has to go back on the machine. I should have this finished up Sat morning and be back onto the intake manifolds and stuff worth taking pics of.
I got a little time tonight and mostly finished up the flanges on the heads, I just need to finish tapping the stud holes....I'm pretty happy with the way they came out. Next it's on the mating flanges for the manifold I think. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Mark- I cannot wait to hear this thing at 9000 rpm. Once Leonardo is finished painting, of course. Taz Terry Phillips
Maybe...but I'm really hoping that between the new million dollar a piece 12 hole injectors, the multi-MAP board, end of pulse timmed sequential injection, and not using a bypass air system for idle so all the air is flowing past the throttle plate I'll get a good result with just 12 injectors. With 24 injectors I wouldn't need to hope, I'd know....but we'll see.
Yesterday I sawed the metal for the lower manifold flanges...then decide I had to clean up a bit and that burned up the rest of the time I had. On past manifolds I've built I've tried doing things a couple different ways. The first one I drilled the mounting holes...and then found that the flange got about .040-.060" shorter after welding and I had to egg the holes to get them back where they belong. The next time I drilled the holes undersize (I needed holes to put the flange in a jig) and then re-did them after welding and that worked ok. I think what I'm going to try on these is to drill only the center hole and leave all the port holes short by about .06-.08 per side and then try to figure out how to do the finish machining when the welding is done.....so, to the shop.
Erik came out, brought beer and helped make chips today. The lower flanges are roughed out and ready to weld the runners onto. Image Unavailable, Please Login Image Unavailable, Please Login
When all is said and done, will you consider taking bids to do similar work for living room centerpieces? It's just so cool to see something like this built from such a ridiculous amount of scratch.
I had actual work work I had to get done this morning so I only got a few minutes in the shop today The first thing I noticed was that the manifolds will need to held on with bolts not studs becasue they tuck slightly under the cam cover flange....I guess the fact that I needed to cut the head with a cutter that could reach under the flange should have given me a clue. Not really an issue but still. I quickly bandsawed a couple runers to about right on the bottom end and they look good I think. Tomorrow I'll cut the rest of them and start welding them on. Once the bottom is tacked on good I'll probably throw it in the mill and cut the tops all the same and tack the top flange on. This should all go pretty quickly and hopefully be done this weekend.

Notch the manifold flange, as surely you are going to lighten this piece anyway? . Infact it would look real cool if you chucked it in the mill and milled it thinner with ribs for strength ... or is that the plan anyway. It would look like a sliding throttle. In fact have you thought about turning this piece into that? Also are your manifold lengths now longer ... ? Pete
maybe. the ears on the head might be far enough off the port centerline that I could cut enough off the falnge to make it clear I'm in get it done mode. The flange will get the same shape I put on the head I think but both sides....I think. The length isn't set yet. I want to put the TBs as low as I can and still be able to get the cam covers off so the runners will get shorter in the next couple days.
The rib idea is very cool, and I do like the machine look as well. So here goes: What if you could machine in some ribs or weld in some stiffeners / supports, then blast the bulk of it with some media that would make it look cast or use a wrinkle finish, leaving the flange ends with the careful machined look. BTW - Sorry to suggest a time consuming effort on top of this incredible project
This morning I band sawed about 3/4" of the lower end and milled the ends square so they will sit straight for welding. Tomorow I'll saw about 1/2" to 3/4" of the other end to make room for the top flange and start welding. I'll set the final top hieght on the mill before I put the top flange on.
