As I (almost) finished assembling my engine and planning to drop it into my car soon I wanted to ask for some comments if there are major scewups in my collection:
late 318 LA-block (factory roller lifters) bored .040 over (after sonic check) mild stroker crank (3,51 stroke... an odd forged piece with 8 bolt flexplate flange) puzzled together with some dished truck pistons @,010 deck height. lightened and shotpeened factory rods with ARP bolts. all internally balanced. comes out to 344cui, 9.5 compression with the heads mentioned below. ARP main studs with windage tray. 302 heads with 2,02 in and 1,8 exh valves (3 angle valve job with back cut... pocket porting... gasket matched to intake) Edelbrock Performer intake Edelbrock Performer 600 carb out of box
Comp CAM 264HR-12 DUR @.050: 210 220 MAX GROSS VALVE LIFT .480 .480 DUR @ .006 TAPPET LIFT 264 274 LOBE SEPARATI 112.0 installed straight (As far as I understood they grind them advanced).
roller rockers with 1.6 ratio (cam specs are with 1.5 ratio)
maybe headers (I have some Hooker comp for B-body around, dont know if they will fit...), otherwise manifolds from a 96 MAgnum 318 which I have in the shelf
std dual exhaust 2,25" (crappy, but already on the car... will have to go when rusted out)
A500 OD-trans (as far as I know has the short 1st od the 999) with stock lockup converter
8.75 with 3.23 gear
vehicle is a 67 Fury III 4dr HT with power brakes and power steering but almost bare bones except of that.
car will be street car except maybe one weekend a year. mpg and stuff dont really matter, just a fun ride, but it has to be able to cruise at 100mph (I am in Germany)
Is there any obvious weak point in here? Dont want to pull the engine too soon after installing it....

Sounds pretty good to me. Maybe I would have chosen even a one step smaller cam, but perhaps the added stroke calms it down a little. Pretty much a sensible engine to take that boat down the road. Should perform decently and have decent fuel consumption. We had a 360 in our '67 years ago, and it worked great. It was just a reringed and slightly tweaked junkyard engine, and hte car run 15.1 at 93 mph in the 1/4 with it. 3310 holley, performer, MP 260/268 cam, homeported adn slightly milled 360 heads with stock valves, recurved distributor, stock cast exhaust manifolds, 2.5" duals, 3.23 sure grip rear. <span class='smallblacktext'>[ Edited Tue Sep 05 2006, 08:25AM ]</span>
Thats good that you know about Comp Cams being 4 degrees advanced,as i don't understand why they would do this, cause you could get in trouble if you didn't.If you just opened the box and installed it and then went another 4 degrees on you're crank gear.....ouch!.I don't think you're headers are going to clear the torsion bars,but those magnum manifolds will work fine,and not much loss in the hp factor.I'm also thinking that that 600 carb is a bit small, but it will give good driveability.It sounds like you did a lot of research on this combo and it looks like a sweet combo.Man this would be a dynamite (can i say that word,or am i gonna get red flagged)combo w/fuel injection or/and a turbo setup.TWO THUMBS UP!. !thumb !thumb Glen
Thanks! I would love to go EFI, but I would have severe problems with getting it inspected. In good old Germany we have very restricitve laws if you want to get some tax exception for "historic vehicles". they have to be close to original... if you make it a custom like you want to you have to pay full car taxes... and as tax here is determined by dis�placement and how "clean" your emissions are a 67 car without cats but a 5.6l V8 engine easily would be 1500+ Euro a year... Lots of cash for junking the carb.... nevertheless I have a distributorless homemade ignition installed which delivers almost all signals to fuelinject it later... would only have to add throttle body and injectors...
