Lordy, the poor man just wants to replicate an existing, proven design & keep the costs as low as possible, yet we have design change suggestions flowing in that, for a private individual, or even a small collective, will blow the cost sky high.

Interestingly, these suggestions, the ones that involve spending so much money, seem not to be coming from anyone who actually put their hands up to buy one.
Just an observation.

Do you mean an open wedge 5k head because there arent any hemi K series except for hybrids with the t series head from what I heard, please prove me wrong!!!!

It would be nice to keep costs down if possible by using some of the mentioned heads rocker gear. The closest one in terms of bore sizes is the Renault 807. However getting rare know unlike the toyota T series.

Also would be interesting if you can get the inlet angle higher like on motorbikes especially the legendary hemi styled honda CBR 1100 and others that are still used for drag racing.

If I had all the money in the world the A series would have this system good ol des!



Another head design that is easy to apply to a crossflow A series is the 3 valve head as in this pic. By raising the inlet ports the 2 valves will work well vertically, creating great turbulence and swirl.



ingenious!!!

couldnt you just have a dummy cam to run all that stuff, like the toyota twin cams run

I think that doing a minor redesign on an existing head is going to be a lot less work & a lot less money than designing a whole new head with DOHC.
Something that looks like a Offenhauser twin cammer would be wonderfull, but the cost would shunt me right out of the game, & as Feral & others have discovered, geting a drive up the front of a A series to a cammer head while still driving the oil pump, distributor, & water pump is not so easy without it becoming a big drama all by itself.

I think that the factory probably came up with the best compromise under the circumstances at the time. It's not like it was a slug, performance wise.

with all this work wouldnt a twin cam option be better

Talk about picky......

If you can I'm sure they would give a good info how toyota has done it.

D, I have a toyota 5K motor with hemi combustion chambers, let me know if you would like some photos or information.

Info:

The modeling is going to take some more time than firstly promised, but this is in favour for all of us.

I'll send mail on the next week when I have made a visiting trip to the manufacturer of our masterpiece.

Yeah its a banboozling site the audio has some kind of infrasound that hits your inner senses in an inexplicable manner.

There are several hemi like 4 cylinder engines that I really admire also like the following which could help in getting the best of this project.

No 1 - Renault 807 pushrod hemi WRC long time winner

No 2 - 800+ HP drag boosted Toyota 2tc and 3tc pushrod hemi

No 3 - all alloy hemi speedway slant 4

No 4 - All alloy aircooled NSU Prinz TT

rest are great little hemi engines but overhead cams.

No 1. - Fiat Twin cam WRC long time winner

No 2. - Hillman imp Coventry climax

No 3. - Toyota 2tg or 3tge

No 4. - Honda civic Gen 1 all alloy 1.3

No 5. - Chrysler galant saturn 1.6 WRC
