budget build 550hp how much $$ are you going to have in the small block.how much $$ are you going to have in the hemi.and then how much money will you have in a 383 400 or 440.
right, nobody said you can't make 550 w/ a SB, but it can be done much easier and cheaper w/ a BB. I didn't add Hemi's because hey are too expensive for most. I've know guys that took a lower milage 440 apart in the grage, re-ring, quick hone, new t-chain, cam, clean up the heads, reassemble add used intake, headers, 750DP and run mid 12's in a heavy B-body. (BTW that's 11's in an A-body) Not going to do that w/ a small block. Not as cheap anyway.

I think some of you need to do a actual price comparison to see whats what... take a head and price the same head in both BB and SB and do the same for the rest of the parts to see what the price difference really is(dont take a cheap 440 part to a expensive SB part... try to make it the same part)... yes I know I can buy the big dollar heads for a SB and have to get all the pricey stuff thats needed to go with them

I think i addressed that in my post, 550 is a 'comfortably attainable' target and probably the best for $$$ per HP comparison. All in all, the stroker shortblocks are going to be about the same cost, again the difference is in the heads....an OOTB Edelbrock BB and SB (for sake of comparison) cost about the same too, but the BB flows enough to make 550HP, the small block really does not....not without about $1000.00 worth of porting and maybe 200.00 or so for higher rate springs/retainers in order for the smallblock to attain the RPM high enough to flow the air needed for 550hp. You can probably/MAYBE make near 550HP with a hydraulic flat tappet cam in a 408, but that would take a lot more porting and in the end it wouldn't be the way I'd go....by comparison I know it's almost rediculously easy to make 550 with a juicer in an E-head soundly machined Big Block. Stock stroke, you can certainly get a 340-360 to the 550 range, again thast's with enough head and RPM but I think it'll cost you more, certainly more than a 440 based motor would at the same power level. Additionally, you can't bring the A motor/A body to B motor/B Body into the equation, to compare fairly it would have to be inthe same vehicle with the only difference being the drivetrain weight itself The small block would have an advantage there in that you can run a much lighter/less power robbing 904 behind one, if it's suitably built. So Again to be fair (if that's what we're really after, not personal preference/bias after all ), it'd be best to back them both with 727's.

Sure if you want to build something supercheap and not put any good parts in it then a big block would be cheaper. But once you start buying any good parts they are really the same.

Weather you chew up the horsepower off the front of the crank or the back with trannys etc the motor still needs to make that horsepower. So that motor see's approx 960 HP worth of stress on the crank rods pistons block.

It may see 960 worth of stress but we know stress doesnt make HP... the engine makes about 820 HP at the crank

At 500hp, you can do an RB cheap, and a LA motor maybe a bit more!! You increase the power levels, you increase the build costs. At these increased hp levels, you'll have to spend more, regardless of block sizes. Oiling systems, must be upgraded due to the increase in engine rpms. Better heads to support that level of horsepower and stronger bottom end pieces, especially the RB. The bottom line is that both the small and big blocks will cost some coin to build at 550-600 hp. If the ECONO route is chosen, then big blocks would have a "slim" margin in price difference to their advantage, power wise, situation may be reversed with the small block outpowering the big block. Strokers are a completely different story, though this thread compares stock stroke motors.

all those pricy parts that needs to be added to the good smallblockheads arent realy all that expensive depending on how you look at it, if you build a motor from scratch and wants good highquality parts all the way it adds up anyway nomather if its exotic heads or not. for an example i dont think jesel or T&D rockers will be much more expensive for a W9 compared to a stock or stockreplacement head
