450+ HP Who has it?
I am getting ready to dive into the books and start researching for a motor in my 86. All I know is that I am going with the superram. I have to at least attempt to keep it emissions legal. I would like to see what you all have done and what products you have used.
Thanks
Doug

Your lucky in having a 86'..450hp will be no sweat..This would be my recommendation (having done this a few times) Pull that 350 out!..Get you a nice 400ci sb, Invest about 700-1000 bucks in a good set of already ported aluminum heads (brodix,dart,bow tie etc.) Put you a nice solid lifter or roller cam with mid 500's lift and you'll be there with out a dout :chevy

I am definately pulling the L98 out. Keep it in the garage or maybe throw it in a truck. I think it would make an outstanding off road motor with the torque and any angle fuel injection.

NO dyno time on mine yet, still tweaking, but think about a 383 stroker with your L-98 engine, with the ZZ4 cam, pretty impressive numbers on desk top dyno. Maybe AFR head's. Know that you are going to have to go DFI or FAST computer. I have heard that the FAST setup is easier to tune than DFI and has diagnositics where DFI does not. Good Luck

Re: 450+ HP Who has it? (Stngray)
The bottom line on engines is it all boils down to $$$. The best bang for your buck is to just install a Lingenfelter top end kit; (Cam, Heads, Super-Ram intake...) This will give right around 400HP. If you are planning on doing a rebuild the next step is a cast bottom-end 383. This will cost around $6,000 for all the machine work, new rotating assembly, cam, heads, and intake. To do the same in Forged pieces will set you back around $8-$10,000. I tend to disagree with using an old 400 block. You'll have to have the thing hot-tanked, brushed, and machined. Probably around $1,000 when finished. You may as well just buy a new Dart or Mowtown II block and build a 427 or 434. The only problem with going to these hi-cubed motors is you'll need a new computer to handle the huge injectors, new cooling system, new clutch or tranny. The cost will set you back over $15,000 but get you over 600HP!!! Goes to prove that the power to dollars cost is exponential!!! :eek: :eek: :eek:
