Thread: 390 Turned 445 Stroked Mudder Project

Tweet

Sorry, I seem to have been experiencing technical difficulties in posting a reply. Tried last night, and earlier today and it didnt seem to work.

Again, tahnk you kindly for the response tech.

Well, yes and no. While i do agree, I should probably explain their side. They are going to junkyards, getting detuned junker 350's for dirt cheap. Im talking 275hp junkers. All they are doing, is bolting on a charger till it blows, and moving on to the next junker block. When i say that, i mean NOTHING else is beefed up to handle it. While i already have the c-6, np205, np208 doubler, d-60 rear, and d44 front built to handle up to 700hp/650tq (original owner's son was going to build a 545 stroker, took the motor).

So, when i say i would like an engine that could keep up with their bolt ons, My target being 400+, i won't be too terribly off from their power output. Being as they wont/cant run even double power, MAYBE 10psi bringing them to about 470? at BEST?

From my perspective, if i build it right, it would come down to driver skills, and frankly they have none :P Great friends, but not great drivers.


Then again, i came asking for advice, i should take it.

What would you say for my build in a non-stroker fashion then Tech?

Though, if you would indulge me, what would you do for the 445 stroker? i have a second motor i would love to build as well

OK, now I understand your position. I guess it's going to come down to a choice of heads. Understand that I'm not particularly an FE guy, but after all, any motor out there is just an air pump and all of them will respond to pretty much the same treatment, air in , air out.

Dave Severson, FFR428 and some of the other FE guys need to jump in here and help if they will. I know the Edelbrock heads make pretty good power, but don't know about some of the other choices like Blue Thunder by A.T. Francis. There may be other heads I have never heard of.

Bottom line, I'll help dial in the static and dynamic compression ratio and run several cam choices through the DynoSim to try to get the motor dialed in once you select the components. As you said, you've followed the Jeff Perkins and Car Craft builds, so you know what kind of power can be generated with the Edelbrock stuff. I'd like to see if some of these other FE guys on the board could come up with alternate choices of parts.

What kind of fuel will be available?

Survival Motorsports is a dealer for Blue Thunder. I was looking on there and there are 3 choices for a small bore FE motor, Medium Riser small bore Quench, High Riser small bore Quench and Medium Riser OE Wedge. You might get in touch with them and find out what would be the best head for your application and what the flow figures are.

Also ask about intake manifolds to match up to the heads......what to use????.....

Well, It would be nice to pull up anywhere, grab some premium, and go. Though i wouldnt mind race gas only...

Scratch that, Pump gas would be highley desireable. I'm going to repaint this beast from time to time, and it would be nice to cruise around, showing it off, without worrying about having a spare can of race gas.


As far as blue thunder goes, wouldnt that be spending about 1/4-1/2 of the budget right there? From what i've seen, they are quite spendy. I understand you have to spend money, to gain power, but wow. I guess i wouldn't be against that avenue though if everything else lined up within budget.

Sorry for the short reply, I'm at work and the boss is in a cranky mood.

Thanks again tech!
