Hi, I have some quick questions. What made you guys decide to go with a big block appose to a small block with a turbo, nitrous or blower. Oh yeah, any regrets on going with a big block V8?

There is no substitute for cubic inches!!! The only thing I regret is that I only have 557 cubic inches!! :lol: But it will be bigger in time!!! :D

Why put a turbo or blower on a 351 when you can put it on a 460!

And you go by the name "Torque321"???? A good big block can make as much power as that small block with a blower or nitrous.....and do it all season long without throwing high winding parts into the bleachers.
Regrets? You bet. I regret not switching to big blocks sooner. There really is NO REPLACEMENT FOR DISPLACEMENT. And when you decide that your big block just ain't gettin' it done, IT TOO WILL ACCEPT BLOWERS, TURBOS, NITROUS..................cool, huh?

I just went 6.31 at 113mph in the 1/8th on the 7th pass ever. Not that impressive until you realize that it's setup for the 1/4 not the 1/8th and it handles 30 mile cruises on the interstate without any issues at all. I haven't even begun tuning on it yet. Big blocks rule!!! Small blocks only rule in road racing not in drag racing. Make the switch, you won't regret it.

My decision was relatively simple. After years of working on, building, tuning, porting heads, etc, etc, the Ford modular engines I had a choice to make for my next race car. I could do one of two things:

A: Single turbo 4.6 or 5.4 four valve engine.
*OR*
B: Nitrous equipped 572-598" big block.

The pro's of the small four valve are: excellent airflow, very responsive to turbocharging, lightweight packaging, a good weight break, and I have an excellent knowledge base from working with them for so long. The con's: limited bore spacing, expensive, puny torque, sky-high rpm's necessary to make power, limited quantities (aluminum 5.4 blocks), not enough weight breaks in enough organizations (most lump them in with small blocks at 3000#).

The pro's of the big block: Readily available parts, proven packages, they like nitrous, great weight break at the right cubic inch, TORQUE, I have a fair amount of knowledge of them, TORQUE, people don't suspect them to be really fast compared to twin turbo small blocks, TORQUE. The con's of a big block: iron blocks are heavy, aluminum blocks are high dollar.

So...I can run a turbo 4.6 @ 2600# OR I can run a nitrous equipped big block (under 600") at 2700#. :shock:

Did I mention torque? :wink: It finally came down to a decision based on overall cost. My father has been running a big block bracket Thunderbird for around four years. Simple 512" with Blue Thunder heads and a glide. The car has no problems clicking off 9.40's at 145 and does it all year long without a hitch. Car was 3050# before this latest revision we've done over the winter. I've seen tons of nitrous, supercharged and even turbocharged small blocks running against him at various bracket races and Fun Ford Weekend series races. They will be working their butts off maintaining their high-tech combo's and Dad will be cooling the car off and having a Coke. No problems. A big block Ford is a well thought out package that makes tons of torque without breaking the bank. We can build his 512" shortblock with simple, off the shelf rods & pistons, a stock block, and an offset ground cast steel stock crankshaft for around $2200. It'll take 7400 rpm shift points and run for over three seasons. About all we do during the bracket season is change valvesprings once. Maybe. It'll go over 150 runs before it needs springs.

Power, torque, cost. Simple choice.

Lets see, the choice for me was really very simple, blowers, turbos, alky and nitrous automatically bump you into the open/outlaw class, where you will compete with stroker big blocks running nitrous blowers or whatever, so you take a small block and put a blower on it, your now forced into a class where your outclassed.
Plus by building my truck for the modified class, I can jump up and play in the open class and get twice the race time.

I dont discredit turbo's, blowers, nitrous, or small blocks....I like them all, and each one has a place where it is dominant, but it came down to what it was gonna take to move 4000 lbs. (3760 without me in it) for the least amount of trouble.
Sure, I could have built a stroker small block to run the same, but it would have been more extreme than the big block.
I could'nt afford a blower or turbo at the time I first built my engine, so I just went with the big blue bottle to help it along!

For me I the BBF was a fairly easy choice. It can easily make the power I want without breaking the bank and parts continously. Personally I don't want to be tearing an engine out and doing a bunch of work on it all the time either. Yes a turbo/supercharged/NOSed SB can make the similar HP but it has to work harder to do it and more $$$ is usually required to get it to that point.

Examine the power to weight ratio needed for your desired E.T. It takes XXX HP. Why start out with an engine that makes ~300 HP when you can start with one that makes ~400 HP? Easy choice.

Last night, I was fortunate enough to understand the true meaning of torque (well, at least I think I did). I went by my old work place at an independent shop to say hi to some of my friends. A customer arrived at the shop to pick up his Pontiac Catalina (not sure on the year), which has a 421 V8. He was cool guy and I ask him he give me ride in his car since I have never driven or ridden in a car with a big displacement V8. After ridden in his Ponty, all I can say was ...DAM! The initial torque just scared the heck out of me. I have driven relatively fast cars (low 11s), which were supercharged small block, but this one was all new experience. Even though it was probably a mid to high 13s car, it was frightening.

Since, I have change my way of thinking, later on tonight, I'm planning on looking for a Ford Fairlane and swap in a 460 big block V8.

And 421" is no longer a big motor. Now think about 521".... or 600+ .....or 700+........IHRA ProStock is now 800+........Omigawd! This big block thing has gotten out of hand!

Bang/Buck

The 385 is king when it comes to bang for the buck. It's a great value.

Just look what you can do with a production block, crank, heads... look in the engine build section.

Go a little further with some simple mods, and you can make over 1000hp on a production block and crank. Try that with production small block parts. The crank I'm talking about here are production steel cranks like the 429 truck part I'm using in my engine, NOT cast.
