The 6G74 and 6G72 heads are identical except for the cams and the distributor.

Ah yes...

However, the reason for the 3.5L camshafts is simple enough, different valve clearances and opening and closing, and then the distributor needs to be changed because the 3.5L camshafts have different 'key' design and the 3G distributor would not fit. |

I would surmise that 3.5L camshafts are different because the timing belt has further to travel due to the increased height of the engine. Yes, the distributor is different due to the key in the cam, but aesthetically the distributors are different as well.

Yes the SOHC 6G74 out of the Diamante is a direct swap. The only thing you run into is changing out the axle bracket in the back.
Diamante guys have been using our 5spd transmissions to do their 5spd swaps for years now. Another note, is that if you retain the use of the Diamante Plenum you can't use the strut bar anymore, but from what it looks like the GT plenum will still clear with the strut bar still on. BTW, where are you getting these images from, is it that one thing you were supposed to send me that time ![]() Regardless, I can get you guys a great price on full 6G74 engines complete with exhaust intake/exhaust manifolds through one of our guys here in Florida. If anyone is interested, I am currently getting 6G74 CP pistons made and if anyone would like to jump on board for a short or long block let me know. http://www.diamanteowners.com/forum/...howtopic=82650

![]() Dude, just putting the 6G74 in a N/A car makes a world of differnce in power. I was considering just dropping another one in the Galant I have too ![]() I forsee this being a very popular path for future 3G owners even if your just going the N/A route. It's best that if you guys want to start doing this, get to the junk yards now because there are 6G74s that these junkyard guys want to get rid of for super cheap. Even if you just do the direct swap it's still waaaaaay more cost effective than even buying an CAI

No shit man. As the old addage goes, "There is no replacement for cubic inches, except more cubic inches." (I know this isnt strickly true)

I know this is kind of geeky to say, but I was absolutely floored when I took the oil pan off of my 74 that it was a 4 bolt main like the 6G72TT engines were.
From what I understand these might be the same engines they use in the 6G74TT ![]() This is our 6G72 2 bolt main

Here is some good information where about 75% documented here sort of gives you an idea of the differences. I can take more pictures of the parts if you guys want tonight.

Probably there would be very little need to replace anything beside pistons on those motors for 500whp. And they would just need machining, balance the rods and the crank with knife edging. And cryo treat them. I think that would be sufficent for those motors. However, I noticed they dont have oil squirters for hte pistons.

![]() I was keeping it on the D/L, but I figure I would at least offer my expertise on the subject of doing these swaps. IMHO I think every V6 owner can afford to throw in a junkyard 6G74 into their engine bay. The manifolds even bolt up to the stock downpipe. The V6 turbo kit even bolts right up to the 6G74 cali spec manifolds.

Where is the oil filter located on a stock Diamonte? Like you say, it wouldnt be in the way of the belts. Im on the hunt for a 6G74 block now.

That makes sense. Like you said this is a pretty easy swap that will result in nice gains. And with the ECU reflash it will run right without too much of a hassle. We can just relfash our ECUs with the Diamonte ROMs.

Horsepower 210 @ 5,000 Torque 231 @ 4,000 According to the results of my butt dyno, the results were quite favorable. Just think how much horsepower headers or an intake gives you. If you can pull an engine for $300~$600 and plop it in your car, you would be crazy not do do this depending on the condition of the engine when you get it. http://www.car-parts.com

The exhaust is in the back of the car, so I don't think that will be an issue, and the CAI would fit as well.

Juan, Tearstones car does not have a 3.5 in it. It is another car that he is talking about. He has seen and ridden in the car personally.
You aren't the only one to do this. |
