I wonder if that was atlantaman's car....he's lives down there and has been working on it a long time??? I think there are only 4 that were ever done and all used the SOHC 330/365 enigines, I think this is the first attempt with a 400/412 engine.

I think you mentioned that somewhere before, that’s going to be a monster…..I like monsters

I put a 500ci caddy engine in a fiat x1/9 years ago.....what a chop-job that turned into. That was almost 20 years ago and take sh*t from my friends about…every time I start a new project, the first question is always, “this isn’t another fiadilac is it?”

I posted a couple here....I don't want to ruin this thread with them


Converting 80s Ferrari into Automatic

The heads came today! Pics when I get home.

It sounds like you just have more sense than me. I see the problem though.....the ports are all pointing in the wrong directions.

Here’s what heads should look like.

I’m pretty happy. It looks like the intake ports are nearly identical to the 308QV and I think the exhaust ports are identical, so I’m pretty sure the flow will come up to at least what the QV heads will. I ran a quick engine simulation using these heads with the QV flow, 360 lift intake cams Russ just picked out and stock exhaust cams…..550 hp.

It looks like external oil return lines will be the way to go, and pretty easy.

I also notice how the cam seals are bolted on, which would make it very easy to bolt on a chain cover box and get it sealed. The only concern I still have with the timing chains is if I can get the chain sprocket lined up with an act of god….we’ll see once the engine gets here I guess.

The real disappointment is the valve covers don’t say ferrari on them. I never noticed that on a tr before and that will just never do…..

I've acquired 4 sets of 4 46mm throttle bodies over the past few weeks. I bought 4 sets because the outer 2 and inner 2 are a little different and I needed to buy 4 sets to be able to make eight 4 sets of 3 or 2 sets of 6. It looks like 2 sets of 6 will be the way to go, I just need to change the spacing between them to match the ferrari bore spacing so I get a nice straight shot for the air going into the cylinders.

Mass Air Sensor are more about emissions than anything else.....if they are small enough to work well, they restrict air flow. For this set-up, I'll be using TPS vs rpm as the primary air measurement with a MAP for barometric corrections. The good is there is nothing in the way of the air so it yields the best hp numbers, the bad is that ANY change to the intake or exhaust path (muffler, air cleaner, ect) means re-tuning just like with carbs….but it makes the best hp

Each one has an adjuster, so you just work your way down the line adjusting. The best way is with a flow meter, but you get plenty close enough buy backing out the idle screw and ajusting them all to be closed, the slighty better way is to crank in the idle screw and set them all to so small opening using a shim (like a small allen wrench).

Yes, they are 4 vavle heads. I measured the cams last night, they appear to be the same lift and duration as 328 cams. I may save the couple thousand dollars to weld and regrind (intakes only, the exhaust cams are fine) and see how they do stock. I suspect the 512TR cams are the same as 348 cams, so more lift and a touch more duration....I may see if I can find a set, I want the lift, but I don't want more duration. I'll have to think about that and may just stay stock for now to keep expenses in check.

edit - I just plugged the stock cams into the simulator and it things I'll go from 554 with custom cams down to 550 with stock....that seems like an awfully expensive 4 hp.....stock it is unless something changes with the head flow or Russ's dyno graph (328 engine, ported heads, custom cam) is just so good I just have to copy (the simulator isn't prefect so the 4 hp could be 14 or so)

I got the heads on the mill last night and mapped out everything that seemed important. It’s funny how they look so similar to the QV heads, but them just odd things will be different.

The TR heads have 7mm valve stems instead of the QVs 8mm, which is actually a good thing since they really only need to be about 4.5mm or maybe 5mm. The intake valve on the TR is about 1/2mm smaller even though it has to feed a bigger cylinder. The QV cam cover has the same bolt pattern, but some reason, the TR cams centers are over an inch wider…because some reason the valve angles are a little bigger (which is the wrong direction for flow). But then the QV head gasket is a perfect match. Strange……

The one things this means I guess is it makes it a bit harder to keep the intake runners nice and straight. Straight will mean the TBs end up sitting at about a 60 degree angle....which will probably mean the 2 banks will want to run into each other nless I put a bend in the manifold runners...oh well, I'm sure it will all work out just fine in the end.

The hose are for vacuum and probably went to a MAP sensor, that's what I'll be using the ports for and maybe the power brakes if I keep them (I'm doing a pretty significant brake upgrade too).

The fuel comes in through rail assembly, the big black things with a screw in them, tubes in betwen. Since I need to change the spacings, I either need to make new longer tube or a custom fuel rail, but I haven't decided which yet.

Sure, stop by. It'll be more interesting in a week or 2 once the engine gets here.
