I have a crate 351W from FMS with 4000 miles.
I did need to change the waterpump/timing cover because I wanted to convert to v-belt.
On the engine stand that was a piece of cake.
I understood a while back you can order the v-belt set up now. There was nothing wrong with the oil pan except to loosen it to remove the timing cover. For personal reasons I swapped the Victor junior intake with a Weaind Stealth. I highly recommend a 650 carb. I went with the BG 650 Race demon. For $4700 this crate motor made 405 flywheel HP or 336rwhp. More than the rated 385....with a high rise dual plane intake. The motor produced 300rwtq at 2800 rpm, peaked at 337 rwtq at 4500rpm and still made 300rwtq at 5450rpm. Wide flat usable power band and very snappy. The next season I ported the GT40X heads for $500. My FMS 351W now made 378rwhp(455+flywheel_ and 361rwtq. It made 330rwtq at 2900rpm, peaked at 361rwtq at 4600rpm and made 330rwtq at 5500rpm. Peak HP(378rw) was raised from 5800 to 6000rpm with head porting. I have pounded this motor MANY times. It is extremely reliable and runs 11.54ET at118mph.
No kicks on FMS 351W crate motors from me.
I could have paid 6500-7K for a local build. Today at $5,200 I still think the FMS 351W is a good bang for the buck. Just makes sure you break it in properly and patiently. Dump the 20-50 break in oil after 500-1000 miles. Move over to synthetic around 2000 miles.

Good stuff!! Being a newbie in the car/cobra world, how exactly do you port the GT40 heads? Does it just open them up to allow
more air flow? Is that something you would recommend I do from the get-go? How did you decide on the Race Demon instead of the Speed Demon or Holleys? Thanks!
