In addition to getting the motor home today, my helper and I got this accomplished.

Looks like a piece of art!! I would have to leave it in my living room for a while just to enjoy the site.

congrats gregg !!!
Its a piece of art !!!

As an added bonus, torque should stay above 400ft/lbs until the 5800rpm range (because of the modified intake). My smaller cam will add more responsiveness to sub-2500 rpm range. So, the usable torque range for city rpms will be quite wide.

Still....If it turns out to be too peaky (having too much mid-range torque), I'm saving an HSR as a backup plan. And, I haven't forgotten how to polish/port.

FWIW: Peak crankshaft torque should be ~500ft/lbs and last from 3400-4800rpms. You should see how the torque curve compares to a stock L98!

Your new engine looks really good Gregg.

I'm sure your going to be pleased with how it runs.

Thanks Will. I appreciate some of the suggestions you provided. I'm really excited to see how the Wiseco's run!

I think you need to make a trip down to Oklahoma after you get it in. Lafleur and I want a ride!

GREGGPENN

I'll meet ya half way! How's Ottawa sound?

USAsOnlyWay

That looks great! Looking forward to hearing how it runs. I've run a similar combo and you will make outrageous torque from 1800-5200 or so. That will be a very fun motor. I wish you luck on your install...hopefully it goes smoothly and everything still looks pretty in the car too!

89Corvette6spdFX3

Well, you will need to break in the motor... an easy drive to Wichita might be better.

tpi 421 vette

Looks really nice I think the combo you put together should work well. It will be a torque monster.

Realize you did a lot of work yourself. Any estimate of cost + time to build out the motor?

GREGGPENN

Tons and tons of time (communicating here, with builders, and best-priced parts-shopping) No way to tell on that one.

80-hrs to port/polish the intake

Cost? Well, I'm afraid to REALLY add up all the parts! (Though I guessed (low) in another thread in General). Everything is new except: Dizzy, Edelbrock base, plenum, lifter retainers/tray, fuel rails, and oil pan. It's unbelievable how the little things add up!

I took about 6mos to research, shop, and buy short-block parts. (That doesn't include the heads/intake(s). Builder took 4-6wks (on/off) to machine/assemble longblock.

Ultimately, buying a rotating kit, bearings, and block (if necessary) would be much simpler -- saving LOTS of time. Part of my problem was I bought the heads and had them angle milled to 56cc for reuse on my OEM 350. Milling was a waste of money after I chose to do the 383. Plus, it made shopping for pistons a bit more complicated. (There ended up being only one "right piston for me and I didn't find it right away. But I found a set on Fleabay and regained milling costs since noone else bid. I got $600 pistons for 1/2 price -- 20cc 4032 Wisco 5.7" rod forged pistons.)

Very nice work!! What are you going to run for a management system?

GREGGPENN

Stock GM ECM (with chip)

Red Dragon On DL

Thats is what my 383 is running, stock ecu & hypertech chip was set up by the previous owner. Not sure if it can handle that looking for more of a custom made chip for this set up.
