heys guys i wanted to build a 468 based on a hi-po chevy build that they did. it pumped out 540 hp and around 536tq. anyways i can fully pull the page down to see all of their specs. so if i cant find them would build would you guys recomend for close results? all you guys with 468s please chime in!!!!:)

anybody?

here's my build but it would certainly be less than 540 horses....maybe around 475 to 500 as a guestimate. 468; 3999289 four bolt main block; forged 3521 crank; SRP forged pistons 10.3 CR; SCAT forged rods; 3964291 rect heads (2.250/1.88); 3933163 intake; Lunati 50250LUN, Hyd Roller, 242/252 @ .050”, .595”/.612”, 110° cam; pro mangum roller rockers; holley 4780, 800 cfm double pumper carb, ARP studs everywhere. as you can tell i like to stay with factory components as much as possible within reason. dont ask me how it performs since it is going in the vette and the vette is still in "assembly mode". like i say i was going for a strong street build with quality components and a pretty respectable rpm capability, but i'm sure well under your 540 horse goal.

sounds pretty good. i want to run this engine on pump gas, and looking for 10.1 comp, anybody else? thanks 79943!

Here is my combo. Never had it on a dyno but with a good tune I would say a "conservative" guess would be around 540-550hp. Starts making "real good" power around 2500, and pulls hard to 6500 rpms. Runs on 92-94 octance pump gas no problem.

454(.030" overbore)
TRW 2349 Forged pistons (10.0-1 cr)
GM 3/8" Truck Rods (polished, side clearanced, shotpeened, SPS bolts)
Ported open chamber oval ports (049 castings)
(2.19/1.88 valves, 308cfm intake, 200cfm exhaust)
Isky Mechanical Street Roller cam
248 deg @.050" intake
252 deg @.050" exhaust
.638" lift intake
.646" lift exhaust
110 deg LSA (4 deg advanced)
Isky Red Zone Roller lifters
Crower Stainless Steel Roller Rockers (1.8 intake / 1.7 exhaust)
JET Stage 2 Holley 4150HP Pro Series carb 950 cfm
Edelbrock RPM Air-Gap manifold
Hedman headers: 2" primary/3" collectors, 3" X-Pipe & exhaust with DynoMax UltraFlo mufflers

This combo is ran through a B/W Super T10, 2.64 1st gear with nodular iron main case & mid plate / 9310 gears, 12 Bolt with 4.30 gears & Moser axles, Hoosier 29.5x11.5 QTP’s

Try this one:

- 468 ci big block, stock rods w/ARP bolts and cast crank
- Edelbrock RPM heads
- Edelbrock RPM Air-Gap intake
- Speed Pro forged pistons 10.1-1 cr
- Speed Pro moly rings
- ARP fasteners
- Comp Cams XE 274 camshaft and lifters
- Comp Pro Magnum roller rockers
- Holley 870 Avenger carb and fuel pump

This combo is very powerful, streetable and very reliable. I love the way it drives and it has excellent manners. I sold this engine to a friend to build a bigger 496 because I am crazy and want more power and I am testing my building skills ounce again.

:D

oh man that engine is gorgous!

how much did that combo put out? man thats a really nice looking engine!!1

ohj yeah i forgot to ask, im gonna put a 2 inch goodmark cowl hood on my el camino will everything clear?

you should see it, hear it and ride in it! AWESOME in every category. That's why my car is at Chris' shop right now getting a 496 and the engine bay detailed, and new gauges. C&D goes the distance!! If I could post a pic of what Chris has done so far to my engine I would.....

i bet it looks killer!

how much did that engine cost?

Mad,

I sent you an email.



Bob,

Thanks for the kind words. Your big, bad, 496 is progressing nicely!!!

at track...a VERY traction limited 13:20
with real tires it's a solid mid to low 12 second car

I basically duplicated the HIPO Checy motor except I used bigger pistons to get the CR up to 10.3/1 and went with a 233/236, .600/.610 112LSA hyd roller. Haven't ran it yet, but can tell you this motor is plenty stout.

whick one did you go with? the 468? i wanted to do that one but i cant pull the whole page down, i dont know why. any one else ? please chime in.

First thing - decide what heads you want to use. Everything builds from there. I picked up a set of new GMPP heads off a ZZ502 motor which are the same as the Edelbrock.

yeah. ive seen some good builds with the edelbrock heads, and brodix heads. i think i will go with thew edelbrock heads. now what? hahaha

heys guys what if i bought a master rebuild kit? then bough those edelbrock heads, and other hi po parts...? would it hold up and would using a master rebuild kit sacrafice any of the power?

sweet!!! any others?

hi!

I got the same tires as you have, but the Sportsman Pro version, what's the traction available when new??? My car's not ready yet, I,m now real nervous about the choice I made!! Please tell me that I can put some power tothe ground with new tires like these!!:clonk:

hey what do you guys think of this hipo chevy 468 build? tons of torque low down and lots of horse power. average toque is 515lbs. now is that too much torque down low? like if i build this engine will it be more of a trailer puller? i know i need torque to get my heavy ass elky going but what do you guys think? that is alot of power..


RPM TQ HP
3000 520 297
3500 510 340
4000 530 404
4500 539 461
5000 525 500
5500 509 533
6000 473 540

Nice Power Curve! Kinda like my 468 combo! :D

Torque is your friend! :thumbsup:

From what I've heard, the "Pro" versions are better then the regular sportsmans....My car is a 95% street car, so traction isn't a huge issue. I've heard the Hoosier quick times are pretty good , and the M/T E.T street are even better..But driving those on wet roads would be tricky!
My post was more so to point out the 468 engine combo and what it was able to do at the track. Woith better tires I would be deep into the 12's
If yours is going to be a street car, I would worry. But if your going to be doing a lot of track duty, I'd consider something else. JMHO.
