Small Block & Big Block Chevy Specific - guys putting my motor for my nova in my truck!!

me and my dad decided to put the motor weere building for my truck in my nova

still dosent have heads and cam put will be getting that stuff next month

going with the dart iron eagle platinum series heads from dart

the specs or @ 700 lift the flow 338 intake/ 227 exhasut

and cam going with a 580 lift solid roller for the street

since it will be daily driven :eek2:

man.........so we have to hear about what heads you are now going with for another month?!?!?!? :jest: well, just my opinion. but if you're going to drop the dough, you really should reconsider at least one more time and go with a set of aluminum heads of your choice and forget the iron stuff. just my $.02. i'm sure others will chime in and agree on this too.

later,
Dave

i would but the 23' aluminum heads dont flow as much as these and the heads are only a grand for the set complete

and also all the other heads is a long story

the afr took to long so canceled and the 18' heads were wrong since the guys at jegs got the numbers mixed up so going with these heads since they flow real good

and also there is a guy in dallas, tx i meet and he has a truck like mine but with a 406 with the same build up running low 7's all motor on pump gas at the track on et streets

that truck is in the 1/8th sorry about the confusion

also u think my truck would be able to handle a 150 shot if i wanted to put it on

Sure you could put a 150 on there.



*Note: I actually have no idea so please don't confuse me with someone who knows anything.

Keep in mind usually an aluminum head will allow for about 1 full point of compression more on pump gas before the dreaded detonation begins when compared to an iron head. I've run both, and I love aluminum heads b/c I can run an 11:1 compression 383 stroker motor on nothing but pump gas, and it runs 7.20s at 94 mph in the 1/8, and that's in a 3500 lb car.

Good luck whatever route you choose, but what are you going to do now for a nova motor?

Derek

but if he's running a lower compression like 10:1 or down he'll actually make more power with a good flowing iron head. at 10:5 it's a tossup either way.

still working on it we just dont know about the motor for it yet were more worried about the body work for now

but probably a 434sbc

how will i make more power with less compression

how will i make more power with less compression

I dont think he's saying ur gonna make MORE power with less compression just that if u had a 10:1 motor the iron head in that case would make more power than the aluminum would

if you are running lower compression you will make more power with an iron head than aluminum because aluminum doesn't hold heat for an effective burn. with more compression you make more power with aluminum because iron causes detonation.

so what is your CR meaning dome height of the piston gasket compression thickness and head chamber. also you can give the roundabout advertised figure if you have no clue.

it will be around 10.4 with these heads which should be good for pump gas

well then the iron heads should work well. question do you know if these heads will work well for you application? you picked a head that flows good cfm @700 lift. WHY? if your running only a 580lift cam why don't you research some of these heads on the market midrange you'll see better power if you fit the heads to your application not just the ones mith the most impressive numbers or the one with the biggest runners and valves.

^^^^I agree completely.

since these heads work the best with the overall displacement of my motor

well then go with a bigger cam or it's gonna be a pig. or research the heads you can't just throw things together. it's all about combination no matter your cid.

i have to call cam motion and get a cam

whats the weight of the truck. whats the trans,rear, suspension setup, converter,tire size, what are your goals, is it street,street/strip/ or race, do you plan to run nitrous, how much of a shot, what is your bottom end, rod length, pistons with valve releif depth,what heads,valve size,combustion chamber springs with install height and seat pressure. may need to be changed according to cam. gasket compression height. what intake and carb.and the big ones CR and CID for a correctly matched camshaft you should know all this and they'll ask you most of this.

i know they already have it set and i have all the answer's for them since they have me on file

also it just my street truck and sometimes maybe the strip

tranny rebuilt th350 with 3400 stall
tires 28x15x10
bottom end is all brand new scat products 4340 steel crank and i beam rods which can handle up to 1000 hp

truck will weigh about 4400lbs

pistons are flat top forged from ross racing pistons and rod length is 6.0 i believe
and intake is going to vic jr 23 and carb is going to be a 750cfm
