Who Is Running A Big Block In Their SPF

Why does every thread you participate in (on multiple forums) lead to you throwing insults?

[fordracing65]

Some people live to shots at engine builders. I don't understand why. Blykins only helps everyone on here for free. And few know more than he does.

Where's the insult? What I posted was factual, all Brent did paraphrase what I said and then add his own spin as if to "correct".

I guess I need to dumb it down a little. BBs as a family have more low end grunt than SBs. If you disagree speak up. SBs as a family make their power higher up in the RPM range than BBs. If you disagree speak up.

You can build any motor to make power where you want but if you look at the population of both, then what you see is what has been stated - the dyno charts don't lie.

Al G, if you didn't have something to b!tch about you wouldn't have much to say at all. A couple of PMs on that other thread early on gave me a heads-up, they were right.

Wrong again. Like Blykins said. It depends on the cam and heads. He can make a small block with more low end grunt than a big block and he can make a big block with more power up top that revs to the moon. Most of the time it is the opposite like you state. But not always the case. So it's not always the case. I'm not taking sides just stating facts.

What part of this don't you get?

You guys are silly.

It would be kind of dumb to build them that way. Lighter engines have lighter rotating mass which is ideal for high rpm work. Big blocks don't need to rev to the moon....at all.....ever.

Bad ass street cruisers are big blocks and bad ass road course cars are small blocks.

Joe,

You got wadded up because someone was comparing an FE to a 302. Then you said we should compare apples to apples, a 427 SBF compared to a 427FE. Then you said that you should google dyno charts for "427 variants" and stated that big blocks brought the power in sooner and petered out sooner.

I responded based on that statement, because I have built many of each. The engine itself doesn't know it's a big block or a small block. It knows how many cubes it has and how big the heads and cam are.

If you meant something differently, then by all means, clear it up.

jacobsed, that's really another wives' tale.....

A longer stroke doesn't make for a lazier engine.....otherwise the 4.750" and 5" stroke Pro Stock Mountain Motor guys wouldn't be able to pull to 8000 rpm.

I have built 408 Windsors that were done at 5000 rpm for towing purposes. I have built 465 and 511 inch FE's that didn't get started until 5000 rpm and would pull to 7500 without issue. If you don't believe me, Google CSX3170 autocrossing. That's a 498 inch FE that makes peak horsepower at 7600......

Speaking in generalities is what can cause problems. As I stated above, engines don't know whether or not they are big blocks or small blocks. The block size itself doesn't mean anything....it's all a combination of bore, stroke, cylinder head, and camshaft.

Yep, couldn't agree with you more.

Maybe Brent needs to hear it from a different source

[blykins]

Maybe Brent just needs to go back to building engines and letting the internet quarterbacks feel like they know what they're talking about.

If you want to see dyno sheets, I have more than I can post....would you believe them? I don't have to Google them.

[cycleguy55]

Interesting how people who have never built an engine know more about it than someone who earns his living by doing just that. <sarcasm>

[blykins]

The generalities are what throw everyone off.

You can't say a long stroke engine can't rev.....because they can.

You can't say a big block has all power down low and nothing up top.....because that's not always true.

You can't say that a small block has nothing down low and everything up top.....because that's not always true.

You can't say that a big block is heavier than a small block....because that's not always true.

You can't say that a big block makes a Cobra handle horribly and makes a poor choice for an engine for a track car....because that's not always true either.

On each and every blanket statement that's made, I can come up with a proven example for the contrary.

By Joe's reasoning, a 427 FE would have a broader powerband, make power sooner and fall off sooner because it's a big block. He fails to realize that a 427W has a longer stroke than the FE (by almost a 1/4"). I guess the FE block gives it a magical quality....

My only point is that blanket, general statements need to be avoided.

[Joe's Garage]

No, the generalities throw you off ...

Nothing surprising here, everybody pretty much gets it but you.

[blykins]

Go pound sand.

You get that?

You don't think that's trying to bait anyone?

Read over what you've posted in a couple of days, objectively, then reflect a little...

PS: Hello pot, my name is kettle... (no not baiting you, just reflecting).

Club Cobra - View Poll Results

PPS: All that poll tells me is that 3 people are honest enough to admit the truth, and the rest are happy with what they chose. I'm not sure of the relevance?

Good luck with your build.

Now that I'm getting older, I'm thinking about downsizing. I'm looking for something with less power, less desirability, something ubiquitous. You know, everyone has one, which will give me anonymity at car shows. Yes! A small block would fit the bill.

Just so you guys know, you're both right in my book.

I agonised for 12 months over this and in the end came down to exactly this point of view.

My small block is coming out and a new all alloy 427 FE being built now, will be going in. It certainly isn't the easy choice because the car is an Autokraft Mk IV with a full inner body, but in the end my mind was made up, for no other reason than the car has the 427 body shape.

[blykins]

Patrick, I must say....

That is probably the funniest post you have made in your Club Cobra career. And you did it with the quickness too.

[Ace23]

Future big block owner chiming in. I like the loud pedal and personally the 427 doesn't get it done for me in regards to pure acceleration. I am by no means an engine guru but based on all the articles and build threads I have seen you can take the exact same engine and by changing cam and cylinder heads completely manipulate the power delivery. I would think with enough cubic inches a big block built to peak at 6000rpm would have plenty of bottom end in our light cars. On a SPF car is it possible to keep the factory hood when you are looking at a 385 series engine? I have heard the intake selection is rather limited......it would be ashame to build something nice and cork it up with a weak intake and airfilter combo. As much as I dislike the thought of having to look at EFI it seems like a multi-port EFI setup would open up your intake options and would allow you to get the proper size air filter on it. If I was buying my car over again I would be looking for a big block.
