Post  georgels on October 28th 2012, 10:13 pm

30 over bore short block, with eagle racing 4.5 stroke assembly all forged 9.5-10:1 compression, custom ground flat tappet 240ish@.50 600 lift, +10 for exhaust@.50, ford racing scj head with valve cut back+blend, weiand stealth with 950cfm holley, 2" headers, 3" exhaust, MSD ignition, 91 octane

4600 lb truck with C6 3000ish converter 4.10 gears, street cruising+commuting 90% racing 10%

What lsa should I run? I going to try for 9.7-9.8:1 static compression

What are some good water and oil pumps for a build like this?

Thanks guys! I know noobs can be annoying lol!

My engine hoist just arrived today! This weekend will probably end up being my engine pull days.

X2 I learned the hard way. I ran a duralast HD water pump and had no cooling issues on a 13to1 compression motor on the street. A good radiator and good fans.

That thing will be making stupid torq. Twisted Evil

I'd say 110 or a 111 LSA. I built my own cam for my 95 f350 I converted with a carb and a killer top-end. I did a 110LSA and I advanced it 6 degrees. When it hits ir will run like no tomorrow down the highway. My compression is just over 10 to1. Thats me though, mabe a seasoned cam grinder will have some better insight for you.

Lem, Randy, Blake comes to mind for cams.

I would probably run it on a 10 and I would also run the stock pump with the pressure raised some.

Its not going to be turning any rpm because of the size of the cam and cubic inch.

The 110 will just help the engine with what it will be good at doing (making torque) If you want to smooth things out down low spread it out wider, but if idle is of no concern keep it on a 110 or lower.

Not really enough information.
What RPM range are you looking to get the most power from that camshaft...?
Do you have power brakes that need more than 12/14 inches of vacuum to work correctly...?
12 or 14 degree intake / exhaust difference with those heads and a closed exhaust system on the street would help.

Oops! Sorry, I want my torque peak to be as low as possible. So I can run my converter plenty close to that peak. This is going to be partly a cruiser so I can't build too much heat in the transmission. I got a plenty big enough booster, I believe, if I don't I'll go to an electric vaccuum.
Thanks for the replies guys! Very Happy

If I bumped up to the P-51 heads, 950 Holley w/ 1" jomar powercone(or do I need bigger?), hydraulic roller cam, and a different manifold, would it still be streetable for 75-100 miles of driving 2 or 3 times a year? Is reliablity going to be risked for that? 80% of those miles would be highway.

Why would you want go from a solid flat tappet to a hydraulic roller?

I meant hydraulic flat tappett because I don't want to be checking and adjusting lash constantly if I'm driving it a lot.

With modern parts your not going to be checking the lash constantly on a milder street flat tappet, thats an old wise tale and cause by using old school factory adjustable rockers.

Not with a roller but I've had good luck with a decent sized solid flat tappet on the street with a ton of street miles. Be careful on break in and run good oil and you won't have problems.

What heads would I use if I wanted to get 700 ft-lbs? My goals aren't very set except for that... Sorry
I really am set on the 545 stroker, dual plane intake, and hydraulic roller cam. I just don't know the cylinder heads to get me to my goal. The horsepower can go wherever it will.

Anybody, I'm looking and the only thing I've found is that longer duration helps torque but I'm unsure of what heads. Help?!?

You can probably get as close to your torque goal as you can with what you have. The SCJ's make as good of torque as any head out there. After you get somewhere between 250 @ .050 and 260 @ .050 you start trading Hp for Torque.
