Silent no longer

I had become excited about an engine combo brought about by a what if and how much dollar for horse experiment. the 352 chevy concept is likely to unleash power in a overlooked area, or rules restricted area.IE large bore/short stroke,with VE running over 100% for a range of RPM that can be expanded in both directions with little work but paying attention to the details.But here is the Idea I want to expand on. what IF we step back in time 1962 take what we know about big blocks and what we know about small blocks build a W series engine and check it against what the current W pro's  can tell us. I had committed my energy to building a 352 but after finding a 1963 chevy2 to build I have no choice, I must build a W engine.  I have studied web sites and will delve into this immediately like there is no tomorrow cause  well nothing could be kooler than a period correct engine, chassis,combo from the early 60's.It's a challenge but a recent magazine build showed the relative ease of a build.parts are available and I will try to keep costs down and not expecting quite the same results, but no one expected to see what the 352 could do either.the W engine is a combination of big and small block.so aftermarket parts are there.  

I've never built one but will research and throw some ideas at you.  

EXCELLENT  

heads are alot of money unless you have some already.

+1, i like the look of the w motors........little 409- beach boys  

notsonew,,,
I also have a 63 Nova and I think it's a great idea and tribute to a great engine that delivered one horse per cube, in the early 60's.
I built a few 348's and 409's but that was almost 40 years years ago.
I'm going to round up info and see what I can find for that ol W and do a dyno sym,,, just fer fun

I havent forgot your project new,still reading up and running numbers but it looks like 500hp is attainable without much effort or cost. How much would you like to see out of it?  

what i've seen so far is 1 h per cube ain't a lot of trouble and you can make em pretty big.a cut down 454 crank 4"and a .125 over 348 block 4.250 is well a 454 so i don't know. wasn't thinking that much stroke tho-366 or 427 crank for 427 cube seems doable a409 block is larger still 4.335. there were 2 big valve heads and one w/smaller valves deemed hi-po so.... other than valve size what were the diff. in 2nd design heads.1st design was discontinued before 1960 so don't worry about them.unless they are better some how.How much can a 348 be safely overbored apparently not to 409 size.they say the old VIKING series trucks(flip front)remember 60-65 &c80 trucks had them.good steel cranks rods were a down fall with very heavy pistons due to combustion chamber design.but one guy uses JE to make his and has weight under control 620-650-gr.edddys are over 800+gr.500-550 horses and450 lb.torque without getting crazy is good. these things like comp. and big cams people are juggling steel and composite gaskets or both looking for correct quench.and the Canadians play with pin heights your looking at a grand with rings pins and locksand like i said thereJE.looks like you can squeeze a 2.11 I-1.7E into the head but any other combo larger is at the others sides loss

I'm not sure about some of the figures you posted about cutting down the 4" 454 crank and a few other mods.
But, a 409 with 4.312" bore and 3.5" stroke comes to 408.9 cubes with piston clearance it's an honest 409.
I used a single plane dual Quad 500 CFM, AFB's (now Edelbrock) 2.19" int. and 1.88" ex.
10.5 compression, big tube headers and mufflers, a hyd cam .520" lift 108 lobe center and 278* duration, valve overlap is at 62*
I managed to get 423 horse at 5500 and 404 ft/lbs torque.
at 6000 hp was 410 and tq was 359 and from 2500 on, the torque was always above 400 until 5600.
I'd post the Dyno sym, but I don't know how yet.
I'm hoping idrivejunk will do it for us, cuz I can email the info to him.
Hope that's what you were looking for.

was working with displacement figures from MORTEC and was thinking of valve sizes that didn't require a lot of valve seat work but this is an area where more could  be better.If you get time run the sim with a3.76 stroke/4.25 bore/then 3.76 stroke/4.312bore.the 409 blocks are a little more valuable.and work for 4 bolt main caps is costly,thus not too much stroke.also thinking cast crank not forged to save on recipt.weight.drop 1 carb go with a 750 single plane look at Breneau eng. parts in Alberta.12.0 to one and 5.50-5.75 on the cam.and thank you very much

Yep.

got home to late to take good pictures phone camera sux got 3 but they are not any count. A man lives 20 miles away and has a room FULL of 348/409 stuff at least 10 of each whole engines and shelf's full of heads and 3/2 manifolds of course 2/4 manifolds but they must be made of gold.he will work with me on a 348 block and some good 409 heads.I think the 409 blocks have gold in them also.got some good info from him and he will be helpful in this build.  

That's good
