Update on the bird and it makes no sense to me. Casting numbers are 488988. YN code on the front. And FROSTY it is not matching the vin. So going forward I will eventually put the 428 in it. And the heads are one of the three. 5C, 50, 56. I only found 5C for pontiac heads. Anyone know more about this situation

Thanks Frosty. The numbers on dash vin is what you are referring to right. Just my thought, the car has been well taken care of and from what my dad told me it is the original 350. But I will check tomorrow

Yeah INDYMANJOE but I've taken that spot now! Behind the camaro is a pontiac 428 XF 62 heads and trans I got the the Firebird or if I can find a 66 or 69 GTO. Thats where I checked INDYMANJOE. So its just a 350 and thats what I've been trying to tell them.

Hahaha thanks JUSTA6. Not seen in the picture is my 68 GMC. And soon to come is my older brothers 61 impala thanks WRONGWAY & RINGO64 nice G6 and camaro.

Thanks, what are you driving?

currently I have what I believe is a 350 YN code. But my dad and a mechanic seem to believe its a 400. I have researched and found no 400 to be a YN code. Also above the YN letters is 0283493. My research says its base 350 with 265 HP. Could I be wrong?

I'm just a guy with a 1968 Firebird. I would appreciate everyone's experience and knowledge with suspension, pontiac engines such as 350, 400, 428, disc brake conversion, etc. Dads Camaro, my Firebird, brothers GTO
