would you use these heads on a 383stroker?

ap72 Personally I'd go with a LQ9 block, forged rotating assembly and CNC's L92's with some really good springs. Its extreemly durable and very budget friendly.

RippinRon The ls2 or ls3 crate engines are a pretty good deal. Great power, flat torque curve and good mileage.

Filmjay AHA! No wonder I couldn't find their site. My lysdexia kicked in every time I tried to remember Scoggin-Dickey and I kept searching Dickey-Scoggin! hahaha!

But, I wanted to stay away from the LS's UNLESS I could build an LS7.

But, after spec'ing out a few different engine combos over the last couple days, I've come to the conclusion that I went absolutely and temporarily insane.

I went "hp-mad" and lost sight of the initial "vision" of the project as a whole...which is the closest replica of a vintage Ferrari that I could build within a certain budget. The original, with a Weber-inducted V12, was only 330 bhp. (rwhp )
So, I've decided to scale back my hp demands to something a little more inline with the original.
With the engines I was putting together, this was gonna be a high-9/low-10 second BEAST! Which, while eternally fun, isn't what I really want in THIS car.

I want it to be a balanced, well rounded, well thought out machine of beauty and grace. NOT a balls-to-the-wall, hair on fire, tire shredding, monster.

So, I think I'm back to small block territory where I was all hyped up about a BBC before.

But, I may still consider an LS. I've found a couple pretty nice examples of a carb'd LS2 that would work quite well. They're at a premium price since they're from Pace Performance, but it can be done. So, I'm going to look MUCH closer at that.

The LS7 block is aluminum...and a bit over $4000.
The titanium connecting rods are in the neighborhood of $350-$400 EACH! (x8 = $2800 to $3200 )And the crank is $1,000.

That's $7800-$8200...and we haven't even touched the pistons, heads, intake, or ignition systems. The turn-key, crate LS7 can be had for about $13K...probably even $1K cheaper if you REALLY look around. But, by the time we get every little thing individually to build it, we won't be saving much...if any at all.

We can buy a 600+hp Gen1 BBC right now for $6000...ready to run. Granted, it's not as "cool" as a modern aluminum hp techno-monster...but it's cheaper and just as fast.
The LS2 block is aluminum and its $1100 SDPC
or the iron 6.0l block for $750. I realize its a smaller bore than the LS7. but you first said you were building a 383. Who said you need the Titanium rods? Its not about being 'Cool' its about a bullet proof entirely NEW engine. That will live at 7000rpm happily.

I'm only limited by what I can fit between the frame rails....within the budget that I've specified for the engine portion of my project.
Though I WILL look into putting an LS motor together. Not that I wouldn't mind having one, I've just thought they were too expensive. Well, that and a LOT of the Z guys are doing LS1 swaps, with the odd LS2 here and there.

Tennessee has adopted nearly every emissions law as California. But, I also don't have to worry in the slightest about emissions since my '78 280Z will be titled as a Specially Constructed '62 Ferrari 250 GTO. THANK YOU SEMA!!!

*edit* - just tried to part an LS7...nope. Can't be done. Half the components aren't even available. And just the block and crank alone are near $6K. I don't even wanna think about a set of titanium connecting rods....
Of course, we can buy an LS7 crate motor for $13-$14K. Not bad, considering the technology. But I think I'll stick to my Gen1 builds. They're cheaper and make more power...with less stuff to break.

HAHA! Thank you.
I conceded to your BBC, and may be changing my entire project around based on it...so it's about time. LOL!

How about those trannys? and differentials?
How much is the total vehicle weight increased.

You are giving me ideas. The last few months I have been leaning toward some project like this.
The Ferrari replica looks great!
I'm using a T5 trans, and staying with a stock R200 IRS. The 5-speed 280 originally came with a BW T5. The R200, with stock half-shafts, were actually "over-built" from the factory and are still being run today in 1,000hp drag cars.
Although, the configuration I've spec'd uses billet braces, mustache bar, and coil overs instead of struts, so that will save a little more weight.
All total, the weight and balance of the car doesn't stray too far from 50/50 and 2600lbs. (w/out driver) The V8 swap, if done correctly, actually offsets the motor about 3/4 of an inch to the passenger side to somewhat account for the weight of the driver. Though some Z purists will argue this point.

It's definitely NOT a cheap project. But, it's definitely cool to me, and well worth doing right.

Considering that I want it to use a domestic engine and look like the vintage Ferrari engine as much as I can...yes, it does indeed.

This looks more like this than this does.

Not lighter. In a V8 swap, after battery relocation, the difference on the front of the car would be less than 50lbs. But the difference is negligible since I'm not building a track car.

Based on stock weights, a SBC is about 40lbs heavier than the stock Datsun I6....give or take. A BBC is about 100lbs heavier than the SBC. That's 140-150lbs heavier than stock. With aluminum heads and battery relocation on a BBC, the weight on the front can be brought down by 130-140lbs....retaining the near perfect weight balance.

stock Datsun L28 I6 - 523 lbs.
stock iron SBC - 575lbs.
stock iron BBC - 685lbs.

Using other lightweight components throughout the engine bay will shave off those extra lbs. Still, I can deal with 10, 20, or even, 30 extra lbs if it means 100 more hp.
