Re: what head and why? afr, brodix, dart pro 1.

I would like to add this build to this thread that used a Vortec truck head.

GM stock 400 2 bolt block bored .030 flat top about 11.2 compression, gassed nitride cast 400 crank, 5.7 p.m. rods with ARP std bolts. Cast iron truck Vortec heads w/ 1.94 in x 1.5 ex, ported, Edelbrock SV ported. Elgin Mechanical Cam (PN 1090) small solid lifter cam .530 in x .550 ex (60"s technology according to Mike Jones Cams). Holley 750 d.p. w/ 1 x 3/4 headers with 3" exhaust. This motor was built to handle a 200 h.p. of Nos. It's in the car but we never hit it. This engine is in a 72 Chevelle, Turbo 400 with a 10" unknown converter and a 4.30 gear. We drove the $hit out of this car. Drove it like we $tole it! With No Tuning, it ran 11.50's at 117 m.p.h. carrying the front tires 10 to 15 ft off the line. With more head work (larger valves) and better valve spring (double). I'm thinking this car will go low 11:00's to 10:80. and still rum pump gas 93 - 94 octane.

Alittle more....

I think this is the one they use. The Blazer has about 3K in everything. I don't know much about the turbo stuff, not the route I am going.

After weighing the options on putting a shortblock together for the top end I have, the 6.0 completely rebuilt and all the swap stuff was over $1000 less. Time will tell whether it puts out any power or not. A few c.i. less than the mud motor, same compression, stock heads that probably flow better than my Performer RPM heads.

I like AFR's. Those 227's are good but I hear the 245's are badass if you have enough motor to use them.

Re: what head and why? afr, brodix, dart pro 1.

Well I have some parts to list on Craigslist and flee bay lol so hope I will get some money to do what I need. Any one wanna donate a muncie to the cause lol I been looking for a reasonably priced one but dang they want an arm and a leg for them now a days, almost worth buying a cheap saginaw or 2 and having one for a spare when the first breaks lol can find those local for $100-300 complete with bell and shifter lol

Re: what head and why? afr, brodix, dart pro 1.

call ron at TRC Trans in chatsworth ca used him for decades. Bet he has a decent rebuilt piece laying around.
Hes fair...and backs his work up (races himself).

Every used muncie I Bought needed a rebuild..sure miss the days of getting lucky for $400 for a good one.
They powershift way better than a toploader type w/hyd clutch that I miss. Wouldnt think of trying that with a T56

Re: what head and why? afr, brodix, dart pro 1.

I've never had a small block but it seems like headers and the exhaust ports are a limiting factor for decent header primary tubes. A friend of my has a 421 and now 427 SBC and I look are the primaries and think there is power on the table. Maybe that is where the different angle heads excel?

Going to try and do the same thing with more head work but stock valve size, goal is to run 10.80's wit the car. Plenum port your Super Victor and watch that engine come alive, sure did with my other SV, sorry I ever sold it.

68Chevele,

What do you different in the plenum on the SV? Do you have any examples-pictures? I'm gonna use this same intake on another 406 build with the GM truck Vortec head.
