A stock 4.3 cap looks just like a V8 cap, with 2 of the little tits plugged with plastic.

The headers are just old SBC cut so there single. The wagon did good wasent allowed to build like I wanted so left rear corner bent a lil weird not bad I had some bigger cars in heat a six Banger Dippy and box Chevy with 3.8 . The 4.3 ran great till roter button exploded.

Hope this helps some of u guys out there. U can get a 4.3 hei distributor off ebay for around 50 bucks plus shipping.And DEC headers make a good set of headers for around 150.00 for them. And to the guys asking about the 3.8 mtr. If anyone had info on them. I ran one for 2 years in about 12 to 15 derbys and had great luck several 1st,2nd,and 3rd place finishes. As far as some things. Such as the heads, intakes and distributors u can change them from a 4.3 to the 3.8 aswell as the cams I found this out on accident. I ordered stuff for a 4.3 I was building and when I got the stuff I realized I had a 3.8 and I called crane cams and they told me the stuff would not work. I checked every thing with calipers and it all was the same as the stock cam out of the 3.8 So I put it together and ran it several times until it finally blew on me at a race that was more like a mud run then a derby. I had to hold it to the floor for a good 20 mins to keep from getting stuck hope this helps some of u guys.
