I have been researching and activley swapping a 4.3 into my 94 ext cab and was following a older build thread but have since lost the URL if someone can help me find it i would appreciate it. THis specific one had pictures of how he mounted his 4.3 ecu behind the glove box and notched it so the glove box still worked he also made a hood cowl for his CPI vortec alimunum intake cover since it was hitting the hood. if anyone has any leads they would be appreciated.
