Dart Iron Eagle Platinum 200cc Guesstimate.
I am planning to build a motor for a pickup of mine and was hoping somebody could run a dyno sim of some sort for me if possible. I would do it myself but i have a mac :(.
350 block bored +.060
Probe forged pistons 6 inch Scat rods
Stock 3.48 stroke crank
Lunati 60103 flat tappet cam In .489 lift Ex. .504 Adv Duration 268 Intake 276 Exhaust .050 tappet lift duration In. 227 Ex. 233
Dart iron eagle platinum 200cc 2.02/1.6 heads
Edelbrock Performer RPM intake
9.73 Compression ratio.
.015 head gasket
.025 piston down hole
Equals .040 quench
Quadrajet carb good for 850cfm will have small spacer under carb. stock bearing clearances.
Just a street/strip motor for fun to build just want to see a dyno graph or even some good guestimates. im hoping for arund 400 horse or more if possible. I may switch to a single plane Victor Jr. Intake if the streetability is OK.

Forgot to add 1 3/4 hooker full length headers into dual 3 inch pipes with dumps after the collectors and hooker max flow mufflers.

Im thinking thats a big load on that solid lifter cam. Make sure you are checking guide holes, pushrod length, piston to valve clearance and coil bind. Go for proper cam breakin with soft springs or 1.3 rockers. 7/16 stud right? Just my 2 cents

Oh my bad i guess i shoulda said hydraulic flat tappet.
its not a solid lifter.

slightly less lift than an LS-3 engine.lesser intake than LS-3,similar heads or maybe better? very free flow headers for a should be close to the same power plus or minus a little.
