Hey are you sure youre not confusing me with Nick -- fourwheeler tv mixed us up. Mine is the green burb, his the orange blazer. I was pretty easy on my burb because I didnt know Id be running and I didnt really have any spare parts.I'm actually running a small block in mine. Its a 383 based on a dart aluminum block with aluminum bowtie angle plug heads. It was a blower motor in a drag car before I got, in a full bodied 73 nova the motor ran low 10's with a blower and different cam. The compression is 10:1, Crane 292 cam, scat internally balanced forged crank, scat h-beam rods. The biggest difference was the commander 950 injection. The motor was way more top end with a carb but with the injection it just pulls hard all the way thru to about 6600 rpms. The motor is an absolute blast at the dunes - 2nd gear 2wd high range everywhere. Having a manual helps with the power too. If youre referring to nicks blazer hes running a 427 I believe, full roller with a big cam and lots of compression ( race fuel required). Hes on here but I cant remember his user name.
