400 h.p is not that hard to achieve. LA eng stroker crank 4 in and +.090 bore job is 400 c.i. Cyl hds flow close to stock edelbrock LA's after a good port job and larger valves.Brand new intake available,modern dual plane.Cams,headers, roller rockers are available.One I was involved with actually made 505 h.p with a roller cam.

I know a guy with a stroker Poly, its 358 cubes and made around 450 horsepower with a dyno queen carb. Head flow was impressive, I think it was around 290 CFM. LOTS of money to make 450 horsepower though.
Now I need to pin those needles, got to feel that heat
Hear my motor screamin while I'm tearin up the street

290 cfm would be VERY impressive but I've never heard of a poly head being that good.

I am thinking more in the 255 cfm range, this is a terrible head to begin with but one of my buddies is trying some new things that we talked about on the heads, should be interesting to see the results.
They sure are fun to play with. The intake that Gary Pavlovich and Roland are putting out is a cool piece. I am going to an LA based engine in the Valiant but I almost hate to pull the poly!

255-260 cfm is correct. Intake side is very good,exh side is similar to an FE Ford and not so good.There is talk of an aluminum cyl head being built.Overall not as bad as people think.

I am late to the Poly party but am here to encourage my friend J.C. and anyone who is interested in building a Poly engine as it is a unique but worthy and rewarding endeavor and we make HUGE average HP & torque with paltry performance parts; IE. 390cid Poly Stroker motor: 4" LA Stroker crank SIR forged rods 234 @ .050" Hyd. flat tappet or 244@.050" Solid flat tappet cam 9.5 to 1 compression w/forged Poly pistons 1.94/1.60" stainless oversize valves 211/164cfm intake/exh. flow @ .500" lift w/stock 1.5 adv. rocker ratio Ancient 1957 Plymouth cast iron Poly dual quad manifold w/500cfm Edelbrocks Homemade 1 3/4" Tri-Y style headers Electronic Ignition with 16deg. initial & 34deg. total advance w/91 octane unleaded swamp water fuel...we achieved the following power: On the engine dyno (break-in numbers only and not fine tuning) we made peak numbers of 412HP @ 5300rpm and 440ft.lbs. torque @ 3300rpm which is nice but the AVERAGE power is where the Poly shines - from 3500rpm to 5500rpm (you can't hurt an engine at that low RPM range) we AVERAGED 375HP and 428 Ft.Lbs. of torque...and still made 391HP at 6000rpm. Those numbers make power EVERYWHERE and will throw you back in the seat and keep you there. We are making about 300ft.lbs. of torque off-idle and about 360ft.lbs. @ 2200rpm and it just climbs and hangs there. However, for the aspiring Hot-Rodder with more discretionary income we do have some "trick" HP parts to make 500-600+HP but it depends on your goals. We also have some future R&D that promises to make much, much, more power but those parts will be designed to blow away some powerful B/RB/and Stroker Wedge engines...but for now we can easily satisfy anyone wanting to make an easy (and HONEST) 420HP & 450ft. lbs. of torque with a "boat anchor" throw-away motor where the cores are "free" and there is no added expense of fabbing & modifying your B-body to accept a Big Block (Big Block Mopars are KILLER engines and if that is the route you want to take, we will applaud & watch you trounce the "other" guys at the finish line - no insults here in our Mopar family). We are approximately three weeks away from finishing the first New Poly aluminum 4bbl. intake manifold in 50yrs. and it is a true High Performance dual-plane intake with modern design enhancements; generous plenum for all HP power levels, tapered & pressure matched runners to prevent A/F pollution of the intake charge during high cam overlap conditions...tall sloping runners designed for velocity and delivering the air/fuel charge as a "straight shot" to the back of the intake valve... We also have T&D bolt on Poly Roller Rocker setups, TTI full-length Poly Headers, High Flowing Gregg Hekimian CNC ported Poly Heads and other great Poly performance "trick" parts...Hekimian Poly Head Flow: 28" of water intake 1.94" exhaust 1.625" 11/32" stems .100" 75/63 .200" 158/105 .300" 218/130 .400" 241/171 .500" 250/192 .550" 256/198 .600" 260/201 .650" 264/205 Take care, Gary Pavlovich glpavlovich@cox.net

JC, Welcome to the world of daring to be different. As Gary P. knows this was the theme of my build from the start. Back in 2005 I teamed up with Bill Richardson owner of Ram Racing Engines to blueprint build what I envisioned as a Rolex Poly stroker. The most difficult part of the project was to keep him from building a full race 500hp racing engine. Cruise nights & car shows is my game now and I live in a Stop Sign and Traffic Light environment. Machine work at his shop within the Terry Walters Racing in Lynchburg, Va. began. The engine has been on the road since Sept. 2010, several members on this site know my car, it has a distinctive sound unlike any other Mopar you've been up close and personal with. Here are some of the specs on my engine using a 1964 318 block, bored .090", stroked to 3.58" making 359 cu.in. Callies Dragon Slayer crank Crower forges rods CP Carillo forged aluminum pistons 9.5 CR Racer Brown ST-14 flat tappet cam 266 deg. .486" lift Howard pushrods, RAM blueprinted rockers 1.5 ratio Weiand 7503 intake REV valves 1.96 in 1.60 exh Mallory 57 distributor TTI headers, 3" Max Wedge exhaust, Spin Tech XL mufflers On the dyno this smaller 359 in. package made 392 hp @5700 rpm, 392 tq. @4200 rpm. This build created an engine that revved up quicker and held a flatter torque cure than a 4" stroke. As for scrapping the Max Wedge project, I just sold my Max Wedge in April. Not to compare the 2, the maxie is what it is, the Poly Stoker is what it is. But when I open the hood the reaction from Mopar or Brand X owners is the same...what is it.

Geez Nick, did Gary P put you up to this, LOL. Jason Rhoades bought my 65 Dodge and now I have the Valiant with the poly and am really liking it oddly enough. I took it to the cruise night in Glendale, California last night and got a ton of positive responses on the poly so I am thinking maybe I should follow your path and ramp it up. Gary does have some cool parts and yours is a good example.
I see you used Bill Richardson, I always thought he was one of the best engine builders that no one knows about, definitely a top shelf guy to deal with!!
Dang it, might just show up at one of the dairy cruises in Danbury with a stroked Poly, LOL

I've known Bill Richardson for many,many years. I drive right past his shop coming to work everyday and going home at the end of the day. I like Bill but I work at a race engine shop myself, so its not logical to use him but I do call him and we sonic check blocks for him occasionally.
I've got the Poly engine out and will take it apart after work today. Lots of parts are already on order but keep in mind this is a cruiser, not a max effort race engine. I appreciate the info from everyone. Keep it coming.

J.C. Next time you see Bill tell him I said hello. I've only spoke with him once since he moved away from TWR and into his new shop. This is a photo of Bill Richardson showing my Poly Stroker on the Dyno, Who's Your Daddy! Nick http://imageshack.com/a/img673/7069/28b8f9.jpg

Joey, A Poly storker in your Valiant, hold on. Sad to say but the Marcus Dairy cruise is just a memory, it's now a new shopping center...Nick
The biggest hold up I have is headers, the stock exhaust hits the torsion bars now so I can't imagine headers will fit any better and I hate to cut the fender wells.
Sad to hear about the Marcus diary, Well! back to brutalizing the Berlin Turnpike!! LOL
