The 243 heads will make a huge difference over the perimeter bolt heads of a 98!!!

Get long tube headers.

I think that is too much cam and you'll just go through springs faster and probably have to flycut pistons depending on lsa. I could see going high 220's or low 230's.

Mill the 243 heads .014 or so to bump the compression. 3 angle valve job that blends the bowl at the runner goes a long way to maximizing the cam.

A yank 3600 is really tight. It will work well with that cam but still drive well.

If you want to go any smaller than that on converter start looking for a smaller cam too and you will be happier overall.

hey Thunderstruck, do you think the Yank ss4000 is tight like the 3600? I mean I know it will feel looser in comparison to the 3600 because of the higher stall rating. But is it tight for being a 4000?

I have a yank ss3600 and thunderstruck is right, its tight. Everyone that has drove my car claims its the tightest stall they've driven. I would really like to move up to the ss4000 but I spray a 150 shot and yank says it would make my shift extension to high. For just a cam or heads/cam setup I'd definitely pick the ss4000 over a 3600

I have not driven or ridden in one with the 4000. I almost upped mine but decided against it. 3600 is plenty to destroy even drag radials from a dead stop on the street and I didn't want to make it worse just to gain another .1 in the 60ft

I will say a Yank 3600 is similar to a Vigilante 3200 in how it drives. The Vigilante 4000 I rode in was sloppy and more than I would ever tolerate in a street car.

Cool. Whenever my car becomes a weekend/track car, I'd like to get a built trans and install that converter. I wanna go 4400 but I think that would probably kill all streetability.

I have that cam, milled my 243s .030, still had .100 PTV clearance. I DD it with a Yank 4000 and would not change a thing. The 4000 is in no way intolerable for a street car, and I would never go tighter on a converter either.

I have a 4000 with 2.73s and I could see going a looser, if I had a cam and 3.73s I'd definitely go 4400 at least. If my trans ever goes I'll definitely go higher, as long as keeping overdrive is an option. Maybe even near a 5000, but that might be pushing it a bit. Stalls really don't kill the driveability for me, it just takes more gas to move. Never really bothered me but everyone's different.

where I live has a lot of hills around town and it makes a larger stall more intense than flat land

Another testimony that a SS3600 is TIGHT (3.42 gear). Only reason I went from a PT4000 to SS3600 was for the "spray-ability".

Yea I could see that being an issue. Around here it's mostly flat, so the highest you'll see is about 3000 rpm leaving a light, and that's more aggresive than I usually drive. Merging on the highway is intense too, at least 3800, usually more.

Again 4000 stall all day!! I went from a vigilante 3200 to a circle d 5c 4000 stall. It drove the same.

If your that worried go with a 3800 minimum..

By comparison with a Yank SS3600, 3.42 gears, 26" tire, and 3800lb weight or so I will be keeping up with or leaving most traffic from a light at around 2200-2500rpm. It is tight enough most of the time it will start to move at 900rpm idle without using the brakes. Around 30% throttle is where you really start to notice it starts to slip more and at anything over about half it will hit close to its 3600 rating and won't flash much higher with more throttle.

One of these days I just need to make a video to help people see how it acts.

BWZ_2k2Z28

I'm putting 3.42s in mine soon. I like the feel of the stall I have as is but I do a lot of city driving so I'm thinking the 3.42s should help me get around town easier. I've never drove a car with a 4000 stall before but I figure if I like a 3600 with 2.73s then a 4000 with 3.42s would be the same or somewhat close. I could always restall the 4000 to 4400 right?

I just installed this cam and I have a yank ss3600 and I love it. Even with the stock crappy 2.73 gears.

Yea I'm running on a 2.73 rear gear, 26.1" tires, and its really not too bad. First drive home I was like WTF, but with a grin on my face the whole time. Now its gotten to the point to where I wished I went 4400 and never looked back, even with the 2.73.


What do y'all 60 at the track? With a 3660 RW I cut a best of 1.77 with slight spinning.

What were your 60s when you were stock motor? I'm trying to see how good my converter does vs others, its a PTC 10.5" custom converter, around 1.5-2.0 STR with around a 4000-4200 flash point. Pretty efficient up top

My car went 11.98 stock motor with converter. I added the cam and have been 11.76. I need to find my time slip from that 11.98 run but it was in the 1.5 to 1.6 range.
