honestly IMo from what I have heard from you, I would do the following. Keep your vert the way it is...it looks really clean...pick up another roller or 4 banger..this way you can concentrate on parts for the conversion car...they can be had really cheap...I've picked up rollers for as little as 50.00 with titles... Start hording parts...trade sell...do odd jobs...beg...what ever it takes to get the V8 parts you need for the swap. Take your time...it takes guys years to put cars together. Parts are fairly cheap and they are plentiful. Build a V8 car on your budget...go to the junkyard....beg for parts here on TR. Hustle is how your going to get what you need...work with some guys here on their cars for trade in parts...help yank some motors or help do some work with them...many have parts and rollers layinig around....give it a shot!! I know Raymond will trade parts for sexual favors...I'm sure he likes young boys. Offer to work his junkyard part time in trade for parts...He may need help..

PS..I'm ALWAYS kidding about raymond...He is my Favorite Cracker.
