Intake manifolds?

[ricechefmerkl]

Need an idea of a great intake man for this 418 windsor stroker motor what is the best one out there for a carb set up its gotta be good to go this these jegs/kasse heads I have coming
Where is a good place the get the manifold what kinda , and keep in mind streetable !!!!

Its going in this 83 capri I got in the works!!!

[MiracleMax]

Not so much a question of how streetable, but rather; What RPM you gonna run, how much air can the manifold handle,ect.


The J/K heads come in two varieties dont they? a street head and a race head (the later being a canted valve affair)

351 stoker to a 418 and want it streetable? You got it asz backwards. Should have stuck with the 302 and stroked that. The only intake I can think of that would be great would be a Victor Jr assuming you built this motor for more of the upper rpm band.

as a VERY general rule of thumb, for roughly every 50 cubes you increase or decrease the motor, the rev range goes up or down by 500 rpm.

This is very general though, so say on a prerformer RPM you would lose 500 rpm or a bit more putting it on a 418, knocking the manifolds rev range down to 6k or below.

I like the victor setups. What carb are you planning on running, A demon Carb would be great on that Motor for sure. Do u have a cowl hood, get a Air Gap design. They are great have raised planes too.

Its not a daliy driver , It more of a street strip car I don`t plan on twistin it over 6500 and if i do there will be a tunnel ram sittin in the hatch back waitin to be put on before race weekends and only that high because of the top dollar bottom end it will get forged the works .. And all i have only heard of one type of those kasse heads I just gettin them through jegs and the one they have listed i`m gettin . The reason for the 351 is that big arm the torque should be rather good i`m jumpin between 427 stroker or the 418 , same price same parts is the big stroke worth it ( 4.100 or 4.170)
for carbs I good been in a family that lives for drag racing we have a couple of 750 , 850 etc everything i would need its just we lack the small block manifolds because of the big block roots like our 600cid 1275 hp 93 mustang car soon to get a 714 aluminim motor we are puttin together to have to go a try I hra Pro mod in a few years once i get my seat time in this capri and the 600 inch

Thanks for the opinions I guess I was on the right track with the victor set up i thought kasse used it for a reason on his dyno testin might as well stay with what works the artical he has on them is pretty cool , We got tons of carbs in the race shop we dont use the small stuff on the race car and our other vuiechle are all ready done so i think w got a few 750`s 850`s holleys up there so i sure i`m good on the carbs

No problem

I am currently finishing up my 414w now, I just need ignition. I run a super victor and 850 demon. with all the torque your gonna make the big victor wont hurt your combo. with those heads and shortblock I think it would be a cryin' shame to put a small hyd. cam in there tough. My .700/.705 solid roller Idles fine at 1,000 rpm. I did try a 950hp holley on the dyno and it gained some power at 6800 but only a couple and the torque down lower suffered. Bill (No head or intake porting almost 600hp NA)

Well i found a bullet proof 427w sroker kit this is looking better i have to go with it now because growing up with my dads 1967 mustang fastback gta dealer 427 side oiler mid rise in it has made me too ga ga for 427 the number just gives me chills .. What heads did you have of that motor?

Definitely put a solid roller cam in there. Like I8URZ282 said.

[jonnyk]

Definitely a Super Victor. If it sees any amount of street use, a solid flat tappet cam might be a better alternative for you than a roller. Solid roller lifters that will live on the street (forced roller bearing oiling) are quite pricey.

[ricechefmerkl]

whats around about number for a set of the solid rollers that will live one the street . You see I am moving up from a Junior dragster and I got every penny it sells for goign into this motor and what ever it takes . So whats a price for some ?

[I8URZ282]

My Crower solid rollers were $450.00, but they should live on the street. Its my understading that if the idle is kept over 1,000 rpm that the likelyhood of failure is reduced on the cheeper roller lifters, but I would probably flip for the good ones. Bill

Spring pressure (for obvious reasons) plays a big part in the longevity of that stuff too. Heavy spings at low engine speeds mashes the needle bearings flat, at higher engine speeds there is less of a sustained load on the bearings so they dont tend to flat out as quickly or at all.

I dont know you finacial position or your willingness to try new technologies (if available for your application, but titanium retainers and conical valvesprings might help in this area.

The idea behind the two is a reduction in mass and a spring that is more resistant to harmonics which allow a light sping with the same or better rev capability.

[jonnyk]

The Crowers do have the forced oiling roller bearings...they should be fine.
