SBF stuff

well its been awile but I finally fired up the 420 and boy oh boy does it sound bad a$$. very responsive and crisp to the throttle. Ended up going with the new AFR Renegade 58cc heads with a super victor intake and an hp1000 cfm holley carb. 2 inch Primary kooks headers with 3.5inch collectors. Bullit did the cam but I think its a moderate one, not all out as I am going to drive it some on the street. The cam card reads dur@.050 is 264in/271ex on a 108 separation with .668/.668 lift solid roller lashed at .026. electric water pump so only running an alt off the crank. don't have the extra cash to have it dynode as I have to build a trans and rearend and 4 wheel disc brake setup and etc. sounds like it will make some big power for sure. any thoughts?

Compression and which afr heads ?

11.14 on compression with the afr 225 renegades. they flow 330 @ .700 lift and 340 @ .800

I would say around 600 to 620 maybe a little more but would need more cam and compression to make 650 to 700 in my opinion. Glad you got it going post some video of if you can or pics.

If tuned well I would guess between 650-675.  If the cam events were right on then it may make more due to compression.  It's definitely an all motor cam as is. I don't think it will take a 250 shot with that cam. Not very good cam timing events for a large dose like that.

Unless I overlooked a post that included an aftermarket engine block, at the horsepower levels you seek and then add an additional 250 horsepower, maybe an quality aftermarket engine block should be on your list!

we did degree the cam to the 104 cl that they told me to. I agree with the cam. I know there is more to be had with a bigger camshaft but will put some time on the motor with the one I have and then call bullit up and have them cut me a new one. If I could get about 700hp out of this motor with a cam swap then I may just forget the nos and have it all motor.

the cam in my 321 is a good bit bigger, I wouldnt hit that with much more than a 175 or so.

who spec'd the cam?

I'm not saying its a bad cam don't get me wrong here. It probably is fine for NA application but it is not a nitrous cam especially on 104cl.

X2 its a N/A cam and 100 shot is all I would want to blow through it . But again it will be fun and you can let us on the out side looking in know how it does.

I wont spray it with this cam. Will run it a bit and when I want more then I will have them grind me a new one. Next on the to do list is build my trans. I have a c4 from Redneck Performance tha I am ging through. Already has a reverse manual VB with a TB and billit servo. I am ordering a propump and a 6 gear planet for it and a hardend input shaft. Still need to find a good kit to put in it as well as have someone build me a converter.

Don't buy the pro pump ! Waist of money ! Use a c5 pump with a c6 pump bushing and get a planet set from jay at broader performance. Ptc or ucc converter . He has a good kit too!

Go to broader performance and yes he has everything you need . I run one of his trans brake vb and planet sets. Good guy !

thanks for all your help and input. Appreciate it.

Time for the switch if you know what I mean.

Not ! 

Im fixing to go drag the bumper off this c4 equiped small lock car
at this no prep race in a few minutes..... Just sayin lol

Stock pump is good w a c6 bushing, dont waste money on a six pinion planet just get a rollerized 3 pinion.

I know but i just like to throw that out there when i can.  Every trans is good for a certain combination and I guess I just know a lot about the sbf/c4 problems I use to have and no longer make that mistake at the 1000hp mark.  Heck he may live up to his word and not ever spray it that hard and be satisfied with an all motor deal.  It would et just fine and live just fine with the c4 then.  

And my guy built that specific trans to begin with so I know what's in it and know the upgrades we are talking about here with it. These guys are right on with their ideas.

If it was mine i would anyway because i would end up changing cam and spraying the crap out of it within a year.  Just seems like a waste to put $1200-$1300 in parts, labor, and new converter for this trans when a glide/converter package with bell for a sbf can be bought for $1900-$2100.  

Great build, carry on!


Good luck tonight Jon.

bout wadded the thing up in the wall lol, was an impressive piece of drivin if i must say.........video to come.

Looks like we need a paint and body section.
