I only want to buy a set of roller rockers once! I need a set that has a warranty if something breaks. For drag racing use only and rpms under 7500. Rockers that are needed are for W-2 Econo heads.

---

Warranty and racing dont go in the same sentence...
you want the best you can afford... I used the old
MP rockers(Crane made them).. they have a roller tip
but the shaft area was no bushing and rode on the shaft
and they worked well for years... now days all I use
is TD rockers... pricey but they work great.. this
pic is the set for a W-2 econo head

I must be missing something here. I thought the kid was on a tight budget and now he's talking $1200 rockers

---

I thought so also but I'm not asking that... he asked
a question.. I will answer to the best of my ability
thats all... then its his choice

Maybe someone knows how to make these type of rockers work under a small block stroker and a 557 or 590 lift purple shaft cam. Rpm range around 6800-7200. Hp maybe like 450 hp.

---

Econo W2 and a stroker, yor really going to have to mess that combination up to have it only make 450 HP using a Mopar cam is a good start to acheive that goal

Your looking to run in the 10's right???
2800 lbs
340
econo W2's
Compression ratio???
With all I have read about your parts the .557 is a very good choice for you....
Check your springs and make sure you are not killing the seat pressure...... aim for 130 to 140 lbs

One thing you may be overlooking is your converter.... have you confirmed you have a good 8" in there........... if not this is where to spend your money.......

Cab, Brock lives app one hour from me and I TRIED to point him in a direction that he could build a low maintenance engine on a budget that would run 10's. Pump gas, 6400-6500 rpm, 520-550 lift solid cam, his W2 heads and a good intake (I like the W2 Victor). Hopefully his chassis works well enough and a 5200-5500 convertor. In his 2800# car that combo should go 10.20's-10.50's

I had to edit this to add that I also recommended using a H beem connecting rod instead of wasting money reconditioning stock rods.

---

If he changes rods will he not need a re-balance??? Good rod bolts and a re-size will work at that RPM.........
What pistons?? how heavy are they??

I ran a .550/.557 Lunati cam in my first 360 and ran Harlan Sharps and never had a problem with them, and know several others that have run them for years also with out failures.
