I m looking for information, or just a picture of a super tall deck merlin block in a 3 rd gen. I want to keep the basic front frame structure, but dont know if its possibly. I have a class drag radial car, with a pa k member, rack conversion, manual brakes, no access etc....but the super tall deck might not fit between the shock towers very well.

any body?

How tall is the super tall deck and why would you want one in a non tube chassis car? When you start getting into monster motor displacements, it's a lot easier to put it in a tube chassis car. Get a tall deck with 5" bore spacing. It's easy to get 800+ CID for $80,000+

I use a Dart Big M 9.8" deck (short deck) for my 540. I can easily punch it out to make a 555 or 565 and could go from a 4.250 stroke to a 4.375 stroke to get a little more out of it. If I wanted to go to a 4.500" stroke, I would have to use a tall deck block since the wrist pin would be too high in the pistons with a short deck.

The hardest thing about putting a tall deck block into a third gen, that still has factory frame rails, is going to be the exhaust. With raised exhaust port heads on a short deck, it's difficult enough to get headers on the car. Using a tall deck block makes it even more difficult. A custom built set of headers will probably cost around $2000.

My 2-1/4" primary tube headers are a very tight fit with the short deck and raised exhaust port heads. I wouldn't even want to know how to do it with a tall deck.

Why, cause sometimes things fall into place.... I can get into a 588-604 (depending on stroke) for less then a new lsx. I build turbo systems, and do headers, so thats not an issue. The car is about as close to being a tube chassis car with out being one...lol. I have a bb 101mm turbo that I d like to run on it, with a small cam, and keep the rpm down, besides the 101 would be small for it anyways, but the block is already 4.6 bore. I can get it down to 571 with a 4.25 crank, but that would love rpm.

Just sounds like fun. I was going to go stacked inectors on the lsx anyways, so the cost is the same on the bb.
